I'm working with some USB drives and trying to troubleshoot a few
problems. MIPS hardware, kernel 2.4.19-rc1 (for the EHCI driver).
I have a USB 2.0 drive that is powered off the USB bus, connected to
an Adaptec USB 2.0 card. When I connect it with verbose USB
debugging messages, I get the following:

Question 1 is, if the device is seen in /proc/bus/usb/devices, why
didn't the SCSI driver map it to a /dev/sdx device? If I remove the
drive and plug in a simple USB 1.1 Flash Drive (16MB), I get the
following:
root@(none):/proc# cat kmsg

<6> sda:
Why do all of the ports change status? What port number am I
actually plugging into? It's not in the kernel messages, but my
serial console reported "hub.c: port 3 over-current change" followed
by "hub.c: port 2 over-current change".
Does the drive draw too much power to use as a storage device?
I'm led to believe that the problem is in this section:
<7>hcd/ehci-q.c: 3strikes
<7>hcd/ehci-q.c: ep 1-out qtd token 801f8049 --> status -71
<7>hcd.c: giveback urb 81608ee0 status -71 len 0
<7>hcd/ehci-q.c: 3strikes
<7>hcd/ehci-q.c: ep 0-out qtd token 00080248 --> status -71
<7>hcd.c: giveback urb 83e2c240 status -71 len 0
What does this mean?
