I have already posted this message in "HID key not accepting..." but I'm not sure this was the good place. So, here is my message ;-)

I'm starting with avr and usb.
I have set up an hardware identical to the usbtiny (without LCD) :
D- -> PD4 (I have added a 3V6 zener)
D+ -> PD2 (I have added a 3V6 zener)
pullup resistor on PD3
status led on PD5
IR on PD6

- Is it a problem to use the D PORT ?

I have build a flash with nothing in it :
- only connectdevice, usbinit, ...
- no IR
- no other functions, etc ...

I have uploaded the hex file to the attiny2313, set the fuse as it's in the doc (using ponyprog)

My device is "detected" by the computer as "1.5 Mb/s"
but I have the same error message

...
usb 4-1: new low speed USB device using uhci_hcd and address 2
usb 4-1: uhci_result_common: failed with status 440000
usb 4-1: uhci_result_common: failed with status 440000
usb 4-1: device not accepting address 2, error -71
usb 4-1: new low speed USB device using uhci_hcd and address 3
...

Is there a simple way to check if I didn't make an hardware / software mistake ?

btw : my mother board is an abit IL90-mv

Thanks
