PIC18F2550 USB Unknown Device
PostPosted: Wed May 31, 2006 4:44 pm     Reply with quote
When i use the CCS example ex_usb_serial.c on my pic and run the program, then windows pops up and says it is a unknown device attached to my USB bus.

Does anybody know what is wrong. I havent changed anything in the example.

this message may have to do with the usb cap being the wrong type, or the osc freq wrong.
