I think the process "vmware-usbarbitrator" is trying to read proc/bus/usb/devices and can't find the file, so when I go to vmware, it can't find any usb devices. > What host os are you using that does not have udev in it? No udev. My own vanilla kernel. > What client os are you using that wants access to the USB ports that is > not working? Is this the latest version of vmware (hint, I have no idea > what their version numbering is, you are going to have to look that up, > but I know they have fixed stuff like this in their newer releases.) It's the latest vmware workstation 8.0.3. The vmware "Removable Devices" tab is not showing any USB devices. > What release of the host os are you running? Linux-3.4.0 with commit 07acfc2a9349a8ce45b236c2624dad452001966b. > If you aren't using udev, what are you using for your static device nodes? Usually, with /proc/bus/usb/devices present, vmware will just read from this file and I get to see the usb devices in vmware. > If you are using static device nodes, why don't you have the /dev/usb/ > nodes on your system (i.e. why didn't your distro create them for you?) Didn't check that as it was working just few days earlier:) >> If I revert back to git pull 3 years earlier, it works. > A git pull of a 3 year old kernel? What are you talking about here? It should have been 3 days ago. Sorry! 3 linux days seems like 3 years in the human time:) Thanks, Jeff -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
