I have been having this same issue, since installing a D Dock APR, and the Dell telephone support was less than knowlegable about this issue, which seems to be common, rather than "I have never seen that before", and "your USB mouse is working so the APR is fine". Disabling the USB 2.0 controller does work, although I needed to switch USB ports to reinitialize the connection. THis is however unacceptable, since it reduces the transmission speed of the USB 2.0 ports, and I do have 2.0 devices, including the T3.
Definitely need a Dell fix to this issue.
I'm having the same T3 problem, and I've upgraded to the latest firmware, latest NSS, etc. No joy. Exactly the same symptoms as others - works fine directly connected to the d600, fails thru the Dport dock. I'm using windows 2000, FWIW.
BTW - my short term solution is bluetooth - I have an Ambicon usb bluetooth gadget that works great.
I also tried to activate the IR port as another alternative, no luck on that either - any ideas?
One more thing - I tried to do the 2.0 hub disable that Rollie mentions in his post on USB 1.1 devices - not sure if the T3/cradle is 1.1 or 2.0 anyway, and my D600 on win2000 doesn't have a 24cd controller - only 24c2, 4 and 7.
Rollie - any ideas on this?
OK, the IR does work - just follow the Dell and Palm instructions - activate it in bios, load the driver (dell) and turn off camea download in control-panel-> wireless (palm) and all is just fine.
IR works great once it's set up - a good alternative to USB until we get an answer on the USB for T3
This issue has been resolved with an updated USB 2.0 driver. The driver is packaged into Notebook System Software (NSS) versions A14 and higher.
The latest version of NSS can be found in the file library using the Downloads under Product Support above.
Last week, disabling the 2.0 controller worked fine, but now, my T3 won't even recognize. I currently have two hardware profiles set up, and the controller is disabled in my default (docked) profine, but active in the undocked profile. I have loaded the latest NSS, but there is no way to verify this. IR sync is very slow, does anyone know how bluetooth compares in speed to either USB or IR. THis may work for the short term.
Dell, it is very painful to have to disengange from the dock, to sync the T3. Please look into fixing this issue.
