I am attempting to connect a Motorola IDEN phone to a Linux box.  Most
of the time I get an error -71 in /var/log/messages. Here are six failed
attempts:

usb 5-1: new full speed USB device using address 2 
usb 5-1: device not accepting address 2, error -71 
usb 5-1: new full speed USB device using address 4 
usb 5-1: device not accepting address 4, error -71 
usb 5-1: new full speed USB device using address 6 
usb 5-1: device not accepting address 6, error -71 
usb 5-1: new full speed USB device using address 8 
usb 5-1: device not accepting address 8, error -71 
usb 5-1: new full speed USB device using address 10 
usb 5-1: device not accepting address 10, error -71 
usb 5-1: new full speed USB device using address 12 
usb 5-1: device not accepting address 12, error -71 

The box is running Redhat Enterprise Linux AS4.0.  I've tried it with
two different phones, three different cables, both 2.6.9-34-EL and
2.6.19-rc6 kernels, two different USB ports, but on a single computer;
all variations show the same results.  Unloading/loading the device
drivers doesn't help, nor does rebooting.  A funny thing about it is
that when I plug the phone into the USB cable, it succeeds about 1/4 to
1/2 the time, whereas when my co-worker does it, it succeeds maybe 1/100
of the time.  I'm told that these very phones and cables work (on
different hardware) under MSWindows.

Is there some more debugging I can turn on or some other way to get more
information about this problem? Does anyone have any ideas what it could
be?

Thank you,
