Remote USB
Remote USB allows a receiver’s physically-attached USB devices to be virtually attached (mounted) to the
sender. This gives the sender direct access to the USB devices, as if the devices were physically attached to it.
See the following list for information about Remote USB support:
●
A receiver’s physically-attached USB devices can be collectively attached to a single sender. The devices
cannot be split between multiple senders, nor can they be collectively attached to multiple senders.
●
RGS supports all four USB data transfer types (bulk, isochronous, interrupt, and control).
●
USB devices that adhere to the USB 1.x or 2.x standard should work. However, webcams and devices that
are sensitive to timing might experience decreased performance, or they might not function at all. HP
recommends thoroughly testing any USB device intended for use with RGS.
●
USB 1.x and USB 2.x devices are supported on USB 3.x ports, but USB 3.x devices are not supported.
●
File copies might take longer due to the additional overhead of the network protocol on top of the USB
protocol.
●
Remote USB is supported for RGS Receiver on both Windows and Linux.
●
Remote USB is supported for RGS Sender on Windows only. Remote USB is not supported for RGS Sender
on Linux.
Conguring the remoting behavior of individual USB devices (Windows only)
The remoting behavior for individual USB devices can be altered from what was set globally during
installation.
IMPORTANT: This conguration requires modications to the Windows registry. Registry modications
should be made with extreme caution, and you should always make a backup of the registry prior to making
any changes.
To congure the remoting behavior of a USB device:
1. Find the vendor ID and device ID for the USB device (see Determining USB device information (Windows)
on page 42).
2. Open the Registry Editor and create the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\hprpusbh
\Parameters\Device
3. Create the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\hprpusbh
\Parameters\Device\VID_VendorID&PID_ProductID
4. For the key you just created, create a string value named Mode.
5. Set the value of Mode to auto, local, or remote.
NOTE: If set to auto, the USB device switches its mounted location between the sender and the
receiver at the start and end of an RGS connection respectively.
