Is it possible force P1010 in USB 1.1 mode ?

Now, I'm using P1010 with EHCI controller under VxWorks 6.9.46.

Due to USB issue, I'm wondering if it's possible to force P1010 to be in USB 1.1 configuration using UHCI or OHCI controller ?

Thanks in advance for your reply,

Regards,

You can also add an external resistor for disabling high-speed mode.

The P1010 USB hardware can be used to support for connection only in full-speed mode. See the PORTSC[PFSC[ field.
