What a Pain In The USB-utt

[Cobra_Phil]

Ioannis,
I am specifically looking for PBP code that emulates a USB Keyboard. Unless I am missing it, I don't see that example in the link you posted. The link you posted has a descriptor file in it, but it is for a vendor defined device.

ReportDescriptor1
; vendor defined usage page
retlw 0x06
retlw 0x00
retlw 0xFF

retlw 0x09
retlw 0x00 ; vendor defined usage

A HID USB Keyboard will have 0x06 as the keyboard defined device. You would be able to plug this into anything that accepted a USB keyboard and it should work.
retlw 0x09
retlw 0x06 ;keyboard useage

DaveC3,
Works like a charm. Thank you very much.

Spoke a bit too soon. Works great in WinXP. Windows 8 is more stringent on USB devices and the current descriptor does not work. But it should be very close.

Hi,
This is something I've had on the backburner for years but, like many others, I've tried USB before and never been able to get it to work (apparently not been motivated enough) so I've been delaying it.
Thanks Phil for starting this thread and thanks Dave for posting the code - much appreciated!
If you get it working on W8, please us know what changes is needed.

Thanks again!
/Henrik.

Sorry, I do not have Win8. Worked on XP and 7.

Take care

Dave

Look on http://USB.org, they have tool to validate descriptors, among other things.
