USBi not working with USB 1.0 connection

Hi,

I recently had a problem while trying to use my USBi interface on an old notebook which is equipped by USB 1.0 interface only (12Mbit).

Registers and single values are correctly read and written, but when I try to donwload the whole program + data ram (several kByte block) the operation fails. The yellow led on USBi continue to blink fast and it never stops blinking. After a while SigmaStudio shows the link communication error message.

Has someone tried this?

Is there any timeout / tweaking setting on sigmastudio? On USBi driver?

Regards

T
