yes2,i can see that
it says unknown usb device (port reset failed)
Good. Now right click on the entry with the yellow (!), select properties.
The 1st tab is the "General" tab, and it will give you a general description of the problem.
Click on the tab "Driver". Then select "driver details". Do you see the "mt7118vu ..."?
If yes, we have locate the problem.
I am pretty sure Y500 in Malaysia don't have Wimax built in (anyone can confirm)?
If we are sure, then you have 2 choice:
1. Disable the driver. Click "Disable".
2. Uninstall the driver. Click "Uninstall".
I suspect this driver get in there because Lenovo is doing a disk image install of OS from a Y500 that may have WiMax.
