Title:
erro connecting more than 4 usb modems "parent hub has no TT"
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
Dear Srs,
I need to connect multiple modems on the same machine but when connect more
than 4 modems appears the following error "parent hub has no TT". I researched
about it and saw some comments saying that this error was corrected in kernel
2.6.36.
I always use the newest version of the kernel that is now
"3.2.0-29-generic-pae # 46-Ubuntu SMP Fri Jul 27 17:25:43 UTC 2012 i686 i686
i386 GNU / Linux" but the error persists. My Ubuntu is 12.04 server, i need
help.
