Ubuntu LTSP Odd Behavior

Greetings.

Seeing slightly odd behavior with server 1.5.2 (haven't tried the latest yet, will eventually). I have a fat client running virtualhere and the machine has some assorted USB items, a multi card reader being one of them.

Virtualhere manifests it as one single device and i can use it and it does, eventually, show up on the Windows host as 4 separate drives (which is correct) however access is sloooooowwwww. And it also seems like it is continually resetting the connection (for lack of a better description) as the virtualhere client window will hang for a second or two then come back. It seems to do this every 20 or-so seconds while using this device.

If i place an SD card into the reader i can eventually mount & access the files but it takes about a minute to open up in Windows Explorer.

Below is some syslog output from the Ubuntu side.

Any thoughts?

Thanks!
Ben
