Updated usbredir packages that fix a bug are now available for Red Hat Enterprise Linux 6.
The usbredir packages provide a network protocol for sending USB device traffic over a network connection and a number of libraries to help implement support for this protocol.
- Due to a bug in the libusbredirhost library, handling of timeouts for bulk transfers did not work correctly. Consequently, traffic of USB ACM serial port devices, such as PSTN modems and SmartCard readers, could not be properly redirected. With this update, no timeout is set on the usb-host side for these devices and the traffic redirection works as expected.
Users who use USB redirection for Spice are advised to upgrade to these updated packages, which fix this bug.
