Hm, I just tried to print from mine on your latest tree, and I have a
stream of:
	[440651.362550] usb 4-1.2: usbfs: interface 0 claimed by usblp while 'usb' sets config #1
	[440656.363409] usb 4-1.2: usbfs: interface 0 claimed by usblp while 'usb' sets config #1
	[440661.364296] usb 4-1.2: usbfs: interface 0 claimed by usblp while 'usb' sets config #1
	[440666.365009] usb 4-1.2: usbfs: interface 0 claimed by usblp while 'usb' sets config #1
	[440677.692298] usb 4-1.2: usbfs: interface 0 claimed by usblp while 'usb' sets config #1
	[440682.693080] usb 4-1.2: usbfs: interface 0 claimed by usblp while 'usb' sets config #1
	[440687.697054] usb 4-1.2: usbfs: interface 0 claimed by usblp while 'usb' sets config #1
	[440692.697784] usb 4-1.2: usbfs: interface 0 claimed by usblp while 'usb' sets config #1
	[440697.698653] usb 4-1.2: usbfs: interface 0 claimed by usblp while 'usb' sets config #1

messages in the log, which doesn't seem good.

Alan, any ideas?

thanks,
