I have CentOS 6.2 x86_64 installed on a USB flash drive (HP v165w). This is the boot drive for an embedded server, using a SuperMicro X7-SPA-HF motherboard.<br />
<br />
This system will stay up for a couple of days, but will eventually crash. The error starts with the following error:<br />
<br />
usb 1-1: device descriptor read/64, error -110<br />
<br />
At this point, the USB device is not accessible. In my case, the system crashes because that device is the system's boot disk! If the system is rebooted, the USB stick cannot be seen, even by the BIOS. In fact, even a full power off and unplug will not correct it unless the system is left for quite some time: even several minutes will not always correct it. However, if the USB stick is put into a *different* USB port (such as moving it from the rear to the front), the system will see it again.<br />
<br />
This is very similar to the reports from users such as this (and others):<br />

In many cases, the recommended solution is to unplug the device and re-insert it somewhere else. That won't work for me: in my case it's not a mouse but my boot drive!<br />
<br />
This error seems to be different from errors such as this one (<a href="https://bugzilla.redhat.com/show_bug.cgi?id=491457">https://bugzilla.redhat.com/show_bug.cgi?id=491457</a> [<a href="https://bugzilla.redhat.com/show_bug.cgi?id=491457" target="_blank">^</a>] ) that occur when the device is being inserted or on boot. In my case, the device is able to be enumerated just fine, and the system will work for several days, but at some point something will happen and the USB stick will be completely inaccessible until the stick is either inserted into a different USB port or the system is powered off for a lengthy amount of time.<br />

I have updated my BIOS to the latest version, and I have tried three different sticks (two different no-name sticks) as well as a different copy of the same model of HP. All have acted similarly.
