  • 1. ActiveSync and multiple PCs
    Is there a way to use Active Sync with one Pocket PC and two desktop PCs. I currently have Active Sync installed on my work PC and would like to install it on my home PC so I can sync my Dell Axim X30 with either of the two PCs. Any clues if this is doable?
  • 2. Need IIS 6.0 Admin Pack on XP to admin SBS's IIS
    When I try to administer our SBS's IIS from my XP desktop I get a message that says, "Remote administration of IIS 6 from IIS 5.1 is not supported. Upgrade to IIS 6.0 Administration Pack." I already have adminpak installed from the SBS's CD. Where can I find the IIS 6.0 admin pack? Thanks!
  • 3. Assigning shortcut buttons.
    How do you reassign the short cut key that is found on the keyboard of most computers that links to the mail program? (There is also one that links to the internet browser). At the moment (in XPsp2) it opens Outlook Express but I want it instead to open Outlook. Thanks, Ben.
  • 4. Not sure where to begin
    I am not sure if the problems I am having are related to the OS, disc, or what. My start menu is missing the bottom left portion, it is white space. (I don't remember what used to be there, but somethint was there!) My computer starts up slower than usual. I can't seem to open more than three windows. If more than one is open, my right click doesn't seem to work. Sometimes when trying to open IE, the top is blank with just the windows icon in the middle of the bar, and it won't load. Norton gives me some kind of error when starting now, and shuts down. Microsoft sends me to the "solution" page and says there is no solution yet, problem is known. I have run anti virus, I have run Adware SE, and Advanced Window Cleaner. Anyone have any suggestions please?????

Problems installing STYLUS CX7800 - USB 2.0 do not recognize print

Installing Stylus CX7800: Windows XP do not recognize the Printer. I connect 
to USB 1.0  (computer default) and also tried the USB 2.0 (using a card I 
have with 2.0)  in both situations, when I go to the Device Manager and 
update the driver (tried use automatic and also pointing to CD) the driver 
fails to install for the Printer Only.  The scanner is working fine.
I have deleted all USB devices, boot the machine. The Windows can install 
back some of the drivers (like the Scanner that is part of this printer), but 
not the Printer.  Any recommendation? 
I lost more than 8 hours trying to fix.. Have gone to Epson, here and did 
not help... 
Bios is updated.. 
I suppose to be a computer expert.... :-))

1.USB 2.0 not recognized as Hi-Speed USB 2.0

Hello, thanks in advance for any help.

I am running Windows XP Pro with SP2.  I have an MSI KT4V series (MS-6712) 
mainboard with a USB 2.0 pinhead.  MSI added a note at the bottom of the 
appropriate users guide page stating, he USB 2.0 technology is downward 
compatible with USB 1.1 spec.  To use the USB 2.0 ports, you have to install 
the USB 2.0 driver, which is supplied by Microsoft for Windows 2000 and XP.  
If you have any problems regarding the USB 2.0 driver, please visit the 
Microsoft Web site.  . . . . 

I have installed a Vantec card reader with a USB 2.0 port, to provide those 
functions accessible from the front of my system.  The Vantec device is 
plugged into the USB 2.0 pinhead on the mainboard. All seems well until I 
plug my new Sandisk Cruzer Micro USB flash drive in the (purported) USB 2.0 
port. I receive a notice from the system reading, gt;!> This device can 
perform faster.  This USB device can perform faster if you connect it to a 
Hi-Speed USB 2.0 port.  For a list of available ports, click here. Four of 
those six ports are taken, and if I disable the fifth and sixth in the BIOS, 
the Vantec card reader lights up but its USB port is dead.  So, one might 
conclude the port is only kind of being identified as a 2.0 port by the OS.  
It is all over my head; thus, I here asking questions.

Having SP1 then SP2 installed, I would have thought this USB 1.1 to USB 2.0 
problem would have been left far in the past.  Is there a USB 2.0 driver that 
would address this?  If not, does anyone have any idea what is really going 
on here?  Does anyone have a solution to suggest, outside of ignoring it?

Thanks Again,


2.Epson Stylus CX7800 Problem

-- If the CX7800 is on, Windows will not boot up during start or
restart.  The CX7800 must be off, then Windows boots up perfectly.

When Epson was contacted, this was their reply.  

"This issue has been reported on the Dell Dimension 4500c and the Sony Vaio
RX series of computers, though it may also occur on some other computers.
When the BIOS of these computers sends the query during bootup to the Epson
multi-function device, the query is ignored by the Epson product which
causes the computer to hang during its boot. This problem has been reported
on some Dell 4500 computer systems using the Phoenix BIOS PLUS v.1.10 A06
ROM chip and on some Sony Vaio RX systems using the Award Medallion BIOS
v.6.0 ROM chip. The best thing we can suggest to do would be to contact
your computer vendor for a possible update\resolution for this issue.

As a workaround, disconnect the multi-function device from the computer and
turn it off. Reboot the computer, then reconnect the multi-function device
to the computer USB port and power it back on. This will allow for normal
operation of both your computer and your all-in-one."  

Any comments or solutions?

3.XP is not reliable recognizing USB 2.0 devices(sometimes recognizes as 1.1)

XP SP2 Pro, i added and installed XP SP2's standard drivers for my 2-
port USB PCMCIA Cardbus adapter, but sometimes when i insert devices
onto it which are really hi-speed devices, i sometimes get ''this
device can perform faster'' message which prooves cardbus controller
is seen in USB 1.1 mode. But the devices are compatible with USB 2.0

But i see ''enhanced'' and USB 2.0 roots successfully and working.
WHY? (using standard XP SP2's drivers).

WHY does XP have much more troubles about USB devices like add-on
cardbus ones?

Components of cardbus: (cardbus made by ''Billionton'')
Standard Enhanced PCI to USB Host Controller
NEC PCI to USB ONEC PCI to USB Open Host Controllerpen Host Controller
NEC PCI to USB Open Host Controller

Thank you.

4.USB 2.0 Scanner on USB 1.1 System (XP): recognized, but does not work

I run a Sony Vaio PC (Win XP, SP1) with several USB 1.1 devices attached.
All fine.
Now I tried to install a Plustek ST48 USB 2.0 Scanner. During set up, XP
gives me a message saying that the USB-device is a high speed device, but
will work, though at lower speed. Unfortunatley, it does not. In the device
manager, everything looks well, no exclamation signs, and the scanner is
listed as functional. Downloaded the newest drivers from Plustek. Installed.
No change. Twain cannot connect to the scanner. To make sure, the Scanner
has enough power, I disconnected all other USB-devices from the machine. No
change. I tried every and each USB-Port at the Machine, with and wihout
hubs. No change.

To exclude that the Scanner or the cable is faulty, I installed the scanner
at a Toshiba Laptop (USB 1.1, Win 200o Pro): it works fine, but very slow
(old machine, little memory). But the scanner itself is ok.

Talked to the guys at both hotlines: Sony and Plustek: both have no clue (as
usual), and point with their fingers to each other.

Now I arrived at the end of my latin. Except installing a USB 2.0 port. I
would want to avoid that, because I use the scanner only for scanning my
24x36 mm slides, when this job is done, I will sell it again, because I do
have an all-in-one HP in my network which has regular scanning capacity.

Almost hopeless, but still: has any of the freaks any clue?

5.USB HDD not being recognized as 2.0

I know this is a hardware issue and not SBS, but how do I get the server to 
consistently recognize my USB external hard drives as USB 2.0?  When I 
restart the server, they are randomly recognized as either USB 1.1 or 2.0, 
and obviously the difference is huge when using these drives as backup 
devices.  The ports are definitely 2.0, but aren't always being recognized 
as such.  Is there a registry setting that could force 2.0?
