TUSB3410: Couldn't link on OS

Part Number: TUSB3410

Hi Sirs,

Sorry to bother you.

We use TUSB3410.

Our OS (Win 7) usually (95%) couldn't detect this device.

There only 5% chance could detect device, but it's will show no driver.

We found there doesn't trigger crystal ( or crystal doesn't work) when OS ) couldn't detect device.

1. Could you help double check our schematic is ok?

2. If OK, How to fix couldn't detect device this issue?

3. How to install driver?

Thanks!!
