HP49G+ USB Communication



  • 1. Keyboard and HP49G+ OS Upgrade from 2.05 to 2.09
    I have an HP49G+ with production stamp 'CN334xxxxx' so the keyboard is less than perfect of course. I currently run OS ROM version 2.05-4 which is an un-official release but I am able to use KEYTIME to make the keyboard actually quite useable. I'd like to upgrade to OS version 2.09 ( official release ) but I'm not sure about the keyboard issue - if I upgrade will the official ROM still allow me to compensate for my poor keyboard with KEYTIME ?

Try plugging in the calc with its power off, then, AFTER its plugged
into the computer, turn the calc on.

Maybe is a fail on calculator, but is improbably because hp49g+ has a
really good quality... hehehehe.....

Hp49g+ is made using the best {*filter*}materials of entire world, hp corp.
process shit and paper together and gets the hp49g+ main board, and
then make the keyboard and overall hardware recicling dettachable
plastic bottles mixin them with residual of hp printer catridges to
get the perfect color.

Try re-installing usb drivers

3.HP49g+ communication and rom update problems

Just bought an HP49g+. Unfortunately the serial number is 52... not
53..., but the keys seem OK. The version is HP-49C, 2.00.

I downloaded the latest USB driver and software from HP. Seems very
buggy to me. I have to try connecting over and over, and eventually it
connects. But it always disconnects after I transfer one thing. (I'm
not using a USB hub). Then after some use, it no longer recognizes the
calc, and I have to uninstall and re-install to get it to show up. Very

To get around this, I got a 256 MB SD card and card reader. That's
working fine - the card and it's files show up in the file browser. Now
I'm trying to update to ROM 2.0.6 (from hpcalc.org). I formatted the SD
card on the calc, then plugged into the PC, and copied the bin and scp
files over. Then I plugged it back into the calc, reset holding - and
+, selected rom update from the card. It keeps saying it can't find the
script file (update.scp). I tried this several times to a freshly
formatted card.

Any suggestions?

4.IR communication between HP48G and HP49G+ ?

I read somewhere that the HP49G+ is IrDA and that the HP48G is not IrDA
compatible. Does that mean that i wont be able to get them to talk to
eachother ? If it is possible, can someone tell me how ?
