Why is 9-12 adapter necessary? For the rsr232 TTL signals?

the cable outputs what the little usb device (in the link) outputs, which is 9v.

Is it possible to use usb 5v by modding the tablet while keeping the serial interface alive for use with a rs232 to usb converter?

Finally got my tablets, 3 intuos2 serial with 2 pens, for 22 euro's Smiley
I didnt realize there are no compatible drivers for windows 7 64bits, there are workarounds, but none worked for me (installing drivers 610-6 in win2000 compatibility, then vista) tried it many times, and on 2 computers, with the same prolific adaptor.
an "other devices" is found called "wacom xd", xd-0608-r in properties, no drivers are installed.

any ideas?

I'm looking for a cheap-ass alternative to teensy, because I need more than one and they are quite expensive here

will this work, hardware wise?

Unless you want to play with the code and adapt it, you must use an ATMEGA32U4-based breakout board.  There are a few of these.

I am curious, how much the Teensy 2.0  turns out to be for you (shipping included)?

Why an ATMEGA32U4? For your code to be compatible?

yeah to directly use it without modifications.  Else, you can use any decent usb-enabled CPU. Of course if you stick with AVR more of the code will be re-usable.

Not all AVR cpus are created equals in terms of USB capabilities. Internal buffer sizes, number of endpoints etc. For typical HID stuff and Wacom it should not be too much of a problem I think. Would have to check the specs for the USB device.
