Hi forgetmex
I can see the message driver with these commands. Is it okay for you?
You can use “lsusb –t” command to verify device EM7455. It should generate an output as below:
tma@tma:/dev$ lsusb -t
/: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=ehci-pci/2p, 480M
|__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/6p, 480M
|__ Port 5: Dev 7, If 0, Class=Vendor Specific Class, Driver=GobiSerial, 480M
|__ Port 5: Dev 7, If 2, Class=Vendor Specific Class, Driver=GobiSerial, 480M
|__ Port 5: Dev 7, If 3, Class=Vendor Specific Class, Driver=GobiSerial, 480M
|__ Port 5: Dev 7, If 8, Class=Vendor Specific Class, Driver=GobiNet, 480M
|__ Port 6: Dev 4, If 0, Class=Human Interface Device, Driver=usbhid, 1.5M
|__ Port 6: Dev 4, If 1, Class=Human Interface Device, Driver=usbhid, 1.5M
/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=ehci-pci/2p, 480M
|__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/4p, 480M
|__ Port 4: Dev 3, If 0, Class=Human Interface Device, Driver=usbhid, 1.5M
The driver exposes device EM7455 interfaces: dev/ttyUSBx
