we have just build a PCB with an Etrax100LX MCM on it and it
works fine, so far. Meaning, the System boots alright.
But every time I try to connect any USB device I get the following
message in an infinite loop:
usb-host.c: USB controller running.
hub.c: new USB device ETRAX 100LX-1, assigned address 16
usb-host.c: Got epid attn for control endpoint, epid 0
usb-host.c: 3rd error for epid 0
usb-host.c: Completing ctrl urb with status -71.
usb.c: USB device not accepting new address=16 (error=-71)
ease, there has to be an answer I'm unable to find!!!
Has anybody an Idea what that could be. First I thought of a Hardware
Problem, but I can't find any bug.
Thx in advance
