Subject: [PATCH 1/5] usbredirhost: Don't set a timeout on bulk transfers
Bulk packets can be (ab)used as interrupt transfers without timing guarantees,
iow you can submit a bulk in transfer and let it be submitted until the
device has data to reports a few eons later.
This is used by (some?) USB cdc-acm devices (modems, smartcard readers, gps
devices), specifically a smartcard reader I've been debugging, which currently
does not work.
Not setting a timeout at the usb-host side fixes these devices. For devices
where timeouts do make sense, the timeouts should be handled by the usb-guest,
which has device specific knowledge we lack.
