v-usb on ATMega168PA
Posted: Thu Jun 24, 2010 9:10 pm
I am running an ATMega168PA at 3.3v with v-usb. I have 100ohm resistors in the d+ and d- lines. d- is ont PD4, and d+ on PD2(INT0). I have read the post about P series chips and have mad changes accordingly so that usbconfig.h has AND usbdrvasm16.S has line 60 modified to be INT0 as well. However when i connect the device to the computer it does not connect. I have tried ALL of the examples and not one of them works. Upon further inspection i found the following output form dmesg(I'm running ubuntu 9.10 also if that helps):
I am at a loss as to what my be going on here any suggestions would be much appreciated.
