I am trying to debug what I suspect is flaky hardware; an ARM (S3C2410) system that normally finds a 4 port hub and two attached devices is now not finding anything. FWIW, I have some debug turned on, and the some relevant dmesg printout is the following (I'll go see if I can extract any info from this):
------------------------------------ Initializing USB Mass Storage driver... usb 1-1: new full speed USB device using s3c2410-ohci and address 2 usb 1-1: device descriptor read/64, error -110 usb 1-1: device descriptor read/64, error -110 usb 1-1: new full speed USB device using s3c2410-ohci and address 3 usb 1-1: device descriptor read/64, error -110 usb 1-1: device descriptor read/64, error -110 -------------------------------------------------- I'm current somewhat crippled since I don't have USB ethernet, but I do have a serial console. I also have usbmon configured in the running kernel. If I could force a re-enumeration of the bus I could collect additional information, but I have a monolithic kernel (no modules) and the physical hub is hardwired so I can't unplug it. Is there anything I can do to force re-enumeration (hub reset?). Thanks for any suggestions, sf ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
