Always run with usb-storage debugging turned on :-) Seriously, a single mount operation does not put a very large load on the system. I would be surprised to find that the timing changes from the debugging code made a significant difference when mounting. Doing lots of I/O would be a different matter. > I hove no such problems with a USB-CompactFlash card reader attached to this > hardware. > > My hardware plattform is a custom specific PowerPC design with an IBM405GPr PowerPC > CPU. > > Here ist my syslog.

Also, can you tell where the mount process is hung? Try Alt-SysRq-T (and make sure you have enabled the Magic SysRq key in your kernel). Nothing else occurs to me, sorry.
