Dear all:
When I read spec there is a term called transaction.
Which one of the followings is the exact definition of transaction?
1. by packet; that means each package sent by host or device will be a
transaction.
2. A in/out pair is a transaction.
3. any behavior before ACK toke.
Appreciate your

Interesting - so coverity doesn't understand the BKL. It
The Coverity checker (and Adrian Bunk) spotted an inconsistent
NULL check of port->tty (it's blindly dereferenced later without
the check).
Alan Cox confirmed the check can go.

This patch (as1038) fixes a bug in usb_stor_access_xfer_buf() and
usb_stor_set_xfer_buf() (the bug was originally found by Boaz
Harrosh): The routine must not attempt to write beyond the end of a
scatter-gather list or beyond the number of bytes requested.

This patch (as1037) makes a small update to the earlier as1035 patch.
The minimum-length computation shouldn't be done in
usb_stor_access_xfer_buf(), since that routine can be called multiple
times for a single transfer. It should be done in
usb_stor_set_xfer_buf() instead, which gets called only

Hi,
This is my first post to this list, so I hope this is an apropriate place
to ask my questions.
As stated in the subject, I am looking for advice regarding USB to serial
(RS-232) adapters on linux. We, at the robotics institute where I work,
have a couple of new laptops lacking serial interfaces
