ULINK2 slow performance on USB 2.0

barry gordon

I currently have two ULINK's and just purchased a ULINK2. My test environment is having two laptops running XP2.
One laptop has USB 2.0 and the other is USB 1.1. Save binary on both machines and the current version of the ARM tool set. Performing a download time test from the pushing of the download button to the completion of the 2nd pass, I'm getting the following (seconds).

ULINK    USB2.0    USB1.1
-------------------------
ULINK2   25.2      11.0
ULINK     9.6      13.1

Both ULINK's (orig) have the same performance within a few tenths of a second of each other.

Both laptops are powered-up and the the USB cable is plugged directly into the root hub of the laptops. I using the same target for the test.

Any similar experiences or suggestions?
