Package: usbip Version: 0.1.7-3 Severity: important
I have two identical USB to RS-232 dongles which I export from one machine to another using USB/IP. The devices appear correctly as /dev/ttyUSB0 and ttyUSB1 when attached one at time with a short delay between them (e.g. 60 seconds). When the attach commands are run immediately after each other only the second device attaches, and a kernel error appears. In more detail... The USB/IP server is Debian Lenny set up using this procedure: http://www.howtoforge.com/how-to-set-up-a-usb-over-ip-server-and-client-with-debian-lenny Although USB/IP is not supported by Debian in Lenny, I feel this bug is unrelated, as the problem appear specific to the client, not the server. Here's the USB state on the server: root@arc:~# lsusb Bus 005 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 005: ID 0557:2008 ATEN International Co., Ltd UC-232A Serial Port [pl2303] Bus 001 Device 004: ID 0557:2008 ATEN International Co., Ltd UC-232A Serial Port [pl2303] Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub root@arc:~# usbip_bind_driver --list List USB devices - busid 1-1 (0557:2008) 1-1:1.0 -> usbip - busid 1-2 (0557:2008) 1-2:1.0 -> usbip root@arc:~# The USB/IP client is a virtualbox virtual machine running on the same hardware.

If this bug extends to the rapid attachment of all types of devices, it may be the same as Debian bug 597161.
