USB instance ID has been changed after USB redirection

An additional suffix will be added to the USB device instance after redirection, it’s expected behavior.

The USB device instance path might have additional characters at the end of the path name

when the device is redirected on 7.6.300 and later version of the VDA. To change this behavior, add the

Product ID (PID) or Vendor ID (VID) to the following registry key:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesicausbbParameters

Name: DeviceInstanceIDOption

Type: REG_DWORD

Value: 0 (default value), 1, 2.
  • If “DeviceInstanceIDOption” is configured to “0” (0 being the default value), devices whose VID/PID pairs are configured to “UsingSerialNumberDevices” use the serial number as the instance ID. Other devices use “serial_number+Bus_number+port_number” as the instance ID.
  • If “DeviceInstanceIDOption” is configured to “1,” devices whose VID/PID pairs are configured to “UsingSerialNumberDevices” use “serial_number+Bus_number+port_number” as the instance ID. Other devices use the serial number as the instance ID.
  • If “DeviceInstanceIDOption” is configured to “2,” all devices use the serial number as the instance ID.
  • All other values are invalid and treated as “0.”
