Subject: Possible bug fix in ehci-hcd
From: Andy Shevchenko <[EMAIL PROTECTED]>
The Sequans company who produce WiMAX chips provides the USB driver and
kthp addon driver. However the USB device doesn't work correctly.
Here is more true hack for Sequans SQN11x0 based modem.
P.S. For more details, please, ask Sequans staff (see Signed-off-by lines).
