A virtual machine software: VMware Workstation 15 Pro
A virtual machine OS: ubuntu - 18.04.4 - desktop - amd64
This two days in a virtual machine install ubuntu - 18 Linux system does not identify U disk problems in the process of, find on the Internet has failed to solve a number of ways, the following is the way I've tried just for your reference:
A, check whether there is the VM configuration USB controller: the VM virtual machine="menu Settings, if there is no this a USB controller, is added, on the right side of the connection box on the hook, the diagram below, I was already set up good, the first method was useless,
Second, check whether there is 10 corresponding Service Windows open, steps: Win + R, input services. MSC enter, open Service window, find the VMware USB Arbitration Service, see if started, if you do not start, will start the Service, the Service is already open my computer, so this method also useless,
Three, online see say U disk didn't mount, need to manually hang, try
$sudo mkdir/MNT/udisk
$sudo mount/dev/sdb1/MNT/udisk
Tip: the mount:/MNT/udisk: special device/dev/sdb1 does not exist
Use lsusb LSBLK order, haven't seen U disk (sdb1), the diagram below:
Four, see online have said to the VM U disk first connect to the virtual machine, try the
VM="menu virtual machine="="mobile equipment connection, the following graph:
Connection is good, already can't see the usb flash drive, under win10 into Linux, the orders to the third step, the result is still the same, this method failed again,
Five, said online and file system format is wrong, my U disk is fat32, this should be no problem,
And said storage module is loaded, modprobe load module also not line,
Finally, in all kinds of test, the USB controller in the VM="USB compatibility is set to 3.0 (see step 1) specific steps, and restart the virtual machine, ubuntu out USB icon on the desktop, problem solved!
