Subject: [usb] USB1.1 Low Speed Issue---HELP!!
Hi all,

I have been trying to make the usb1.1 core work in low speed but
without success. It runs fine in full speed @ 48Mhz clock but it doesn't
repond at low speed (I assume its a 6 Mhz clock we have to use!). I get
no response from the PHY and I guess no low speed logic as been
implemented in it.

I know the J & K state are supposed to be inverted for low speed but
after reading up on the USB1.1 Specification, I'm still not clear weather
it is the job of the HUB or the USB DEVICE to invert the logic.

Any help or hints would be greatly appreciated
