Mass storage failure during USB2 data transfers

 Hi guys,

 We have a long standing bug report against Mandriva kernels which
is also reproducible with vanilla kernels.

 Looks like the device gets resetted after trying to copy aprox. 1.3GB
of data:

"""

 On this URL:

http://qa.mandriva.com/show_bug.cgi?id=22790

 You'll find full hardware info and several test reports made
by the reporter. The ticket is pretty old, I recomend start
reading the most recent comments.

 The reporter is being CC'ed, his name is Jan. If you have questions
ask right away.

 Thanks,
