Hi,

I'm working on supporting an ePad USB (electronic signature device) device
from Interlink Electronics on WinXP pro and Win 2003 server platforms. There
is a software given along with the device for testing. This USB device
belongs to HID class (deviceclass - 0x03, deviceSubclass - 0x01,
deviceProtocol - 0x02). When I plugin the device to a standalone pc and open
the application, everything works fine. Now if I do an RDP to this system and
try to use the same application over RDP-
1) On XP pro systems, it successfully opens a handle. However HID data is
not shown by the application
2) On Win2003 server machines, the same application works fine!!

Is there any known problem with HID devices when I do an RDP on XP clients?

Any comments are welcome.

Thanks,
Sri

Which server are you connecting to ?
Which version of mstscax.dll are yo using ?

Version 6 of mstscax.dll supports USB device redirection
(for certain classses of USB devices) if connecting to a Vista/WS2008 server
properly configured.

On average, if you have a HID device on the display machine running
matscax.dll, then, what happens is that mstacax.dll get a bunch of raw
mouse and keyboard event messages, and, those gets sent to the server
to the keyboard-class miniport driver that disguises remote input devices
as some form of PS/2 devices to the server.

So, the server nevers sees the input as coming from HID, but, behaves
normally in general.

Ivan,
I'm testing this device on 2 platforms - WinXP pro(SP2) and
WinServer2003(SP2).
I'm using RDP5 ver 5.

Is there a way to support these kind of devices on RDP5? Any hack/workaround?
If I upgrade the RDP to ver 6.0, would it work on XpPro? (I cant ask my
clients to do this anyway!!)

Thanks,
Sri
