I’ve been using vmware server quite a bit of course, I’ve mentioned it before. I had never played around with accessing a usb device in the guest environment though. When I tried (host operating system is Mandriva 2006)…. nothing was listed, in spite of several devices being plugged in (and unmounted from the host.) So, I looked around and found that according to this…. that vmware feature requires USBFS to be mounted on /proc/bus/usb …. Some systems that don’t do this by default are…. Ubuntu Linux 6.06, SUSE Linux 10.1, SUSE Enterprise Linux Server 10, Mandriva Linux 2006, SLES9 SP3 64 bit……………. so how do you fix it?
