Hello, I have interesting problem, which I don't know how to solve. I do the whole setup on the target, and connect target with my desktop. On my desktop I use VMware with RHEL Guest OS. Once I issue: modprobe g_zero I see on the desktop usbtest.ko inserted in the list of modules (hot plug). I also see the USB gadget in /proc/bus/usb/devices . I setup the same on my laptop. Interesting enough, although laptop recognizes USB keyboard and mouse on all ports, it does NOT recognize hotplug (does NOT insert usbtest.ko) when I issue modprobe g_zero?! I do not see the USB gadget in /proc/bus/usb/devices . I did mounting of usbfs by myself at the beginning on the host side, issuing (as root):# mount -t usbfs none /proc/bus/usb What can be the list of potential problems for such a behavior?
