[Bug 252341] Re: USB devices fail after suspend

[Marco Steinacher]

I can confirm that this bug still exists in Karmic 9.10 (64bit) running
Kernel 2.6.31-21-generic on a Lenovo ThinkPad T410.

The workaround (unloading and reloading the ehci_hcd module) works, BUT
this requires the compilation of a custom Kernel with ehci_hcd as
module. In the current standard Kernel it is compiled in and not loaded
as module which makes the workaround useless. Is there a reason why the
ehci_hcd is not available as module anymore?

Thus, a "fix" of this bug would be to include ehci_hcd as module in the
default kernel. Affected users can then simply add ehci_hcd to
SUSPEND_MODULES to solve the problem.

Note 1: Bug #95144 might be a duplicate of this bug.
Note 2: I know that the Lenovo T410 is affected by another supend-resume bug (#) which will hopefully be fixed soon by a BIOS update. However, I suspect that the USB issue is not directly related to that. If the upcoming BIOS fix solves also the USB problem I will report it here.
