[THIN] Client and jump drives

Running PS 4.0 on W2K3 servers. Connect client drives at logon is
checked and there are no GPOs blocking this. I can successfully map com
ports but when I try to map a USB jump drive, it does not map. Fails
with system error 55. I've tried with the USB drive in place with an
assigned drive letter and then logging into a Citrix desktop. From the
command line, issuing the following net use E: \\client\h$
<file:///\\client\h$>  fails. 

 

Any ideas? Has anyone gotten USB jump/flash/thumb (insert name here)
drives to work in an ICA session?
