 |
|
Is it any way to force system (hal or udev) to reread usb bus?.
I want to do this to mount usb devices that were removed by eject command but which are still connected to usb bus, or
to mount usb devices that were used in VirtualMachnes. (vmware remove device from system while using it in VirtualMachine environement)
If this is possible it prevent me from re-pluging device.

No, it's not working.
This is when I plug USB device first time

So now, the device is plugged in (as it was all the time) but i can't see it in my system. I'd like to make this device visible again for my linux.
