[27132.350063] hub 5-0:1.0: unable to enumerate USB device on port 1
When I plug in my avr using a USB 1.1 Type B socket i get the above errors within the dmesg. Any ideas I've double checked my circuit I can't see any obvious errors.
I'm using zener diodes method as my circuit supply voltage is 5v. They're rate for 3.6V at 0.6W. I'm trying to use BOOTHID bootloader so I can upload my firmware via usb. I have the firmware flashed onto my chip. I'm using a 20 MHZ crystal. It's setup as a full swing oscillator.
