Unable to mount USB drive on Wyse V10 thin client via RDP (vmware ESX 3.5 virtual machine)

I have a Wyse V10L thin client connecting via RDP to a VMWare virtual machine.  I need to be able to plug in a USB drive and have it be recognized as a disk on the virtual machine.  The specs for this Wyse thin client state that USB redirection is supported with RDP, and the Auto Connect USB devices check box is checked in my RDP settings on the thin client, but I can't get the VM to see the USB drive.  

I also tried this with VMWare View - same result, no USB drive connection.  We are not using the Wyse TCX feature, and that is my next step, but the specs say it can be done with just RDP, and I've read other forums where others were able to get this to work.  Any info would be appreciated.

What happens if you plug the USB device BEFORE you connect to the XP host?

I've tried that - same result.  Also tried plugging it in before starting the thin client itself.  The thin client recognizes the usb drive in the startup log, but nothing on the VM.  
ESX 3.5 Does not support USB. Because vmkernel does not have USB detecting module in it.

This has nothing to do with ESX 3.5. This is an RDP feature to access things like drives.

Looks @ the details in below mentioned KB article

http://kb.vmware.com/1015

From your post I understand that your VM is hosted on ESX 3.5

I hope this answers your query.
Could you try doing the same but from:
- Windows XPe thin client (I assume yours is Linux)
- Full Windows machine (XP, Vista, 7)

If it works on both, your issue is the OS on the Thin Client. In this case check if there is a new firmware available from the thin client manufacturer and upgrade accordingly.

Thanks for that info.  Correct me if I'm wrong, but VMWare View is supposed to support the USB redirection, though - right?  Even if the VMs are based on a ESX 3.5 infrastructure.  I was having problems redirecting with View as well - just wouldn't see the device.  Can you offer any tips on doing this without having to get the Wyse TCX server?  
@ tsmvp:

However this VM is hosted on ESX 3.5, In that case VM will not have USB controller in it.

@nithinprabhaka  that page no longer exists.  
I asked you to test with a different thin client as I do think the issue is there. Regardless of what is supported, the thin client OS must be able to handle not only at the local OS level BUT also with the appropriate plugin from the vendor (i.e. VMWare View Client, Citrix Online Plugin, etc).
If this is indeed Linux it means the RDP client is NOT official (meaning not from Microsoft or a licensed third party - it is probably based on RDesktop) what usually means not all features work as expected.
I do know VMWare VMs WILL work with this as I run mine under ESX 4 (ran on 3.5 before) and I use Citrix XenDesktop and that works just fine.
Again, test from a Windows machine or a Windows XP Embedded thin client with the latest RDP 7 client. If it works your issue is the thin client OS.

@nithinprabhakar Does not matter. This is NOT USB redirection. This is a drive. Drive redirection over RDP does NOT rely on USB.

@ pmcilvaine:

USB redirection is supported in vmware view 3.0

Can you help me with the vmware view version?

I do not have much knowledge on VmwareView, though I will try to help you

@nithinprabhaka    I do have VMWare USB controllers in the device manager of the VM, which I believe were installed/enabled by the VMWare View agent installed on the VM.  They are called VMWare View Virtual USB Device Manager, and VMWare VIew Virtual USB Hub

I'm using VMWare View version 4.  
ok, I understand, in your first post you did not mention that you have vmware view so it lead to bit confusion.

@tsmvp  I will give that a shot.  I don't have any Windows-based thin clients.  Would that test be possible from a Windows XP computer (thick client)?  
For sure. Test from a thick client (regular PC). Make sure you use the latest RDP client available.

Do you get any error message ?

@nithinprabhakar:   I have been trying both methods - using regular RDP and using the VMWare View connection broker.  Both unsuccessful :-/

@tsmvp   the thick client was able to connect to the USB drive.  What do you think I should do with this Linux/Wyse ThinOS.....   possibly a patch or firmware upgrade?  They already have a pretty high version.  
Well now we know for sure the issue is the Thin Client. Try to get a newer firmware on it and if it does not work, call Wyse. Their support is usually very good and may be able to help you out.

Had to call WYSE customer support to resolve the problem.   Suggestions were helpful but ultimately did not work.  
First of all please post the solution you got from Wyse so everyone can learn.
Finally, I disagree with your comment. The suggestions were spot on. My last reply clearly mentioned the issue was indeed the thin client and that a call to Wyse should be made.
Your closing comment was 'Had to call WYSE... to resolve the problem', EXACTLY as suggested. So I cannot really see why the suggestions did not fix the issue.
No one here works for Wyse and if there is a problem with their devices that we identified, it is clear they are the only ones that can fix it.
It is like you having a car that is not working properly and after troubleshooting we tell you we do think the issue is probably with the fuel injectors. You go to the mechanic, he diagnoses the issue as being the fuel injectors, replaces them and your car works perfectly. Then you come back here and say our suggestions did not work and that you had to take the car to the mechanic...
I do not mind helping around (and that is the main reason why I am the top poster on the Remote Desktop forum) but comments like this are really not appreciated.

The solution was to purchase and install the WYSE TCX client add-on.  No firmware upgrade was required once the TCX client was installed.
