<DIV>There was a relatively big change in ohci-pxa27x driver, I think</DIV>

<DIV>You need also to configure those gpios to alternate function 2 in the MFPRs.</DIV>
<DIV>If you use a transceiver mode, then may be you need USBHPEN signal</DIV>
<DIV>connected to your PHY and configured accordingly in MFPR.</DIV>
<DIV>Also, in pxa310 there is a U2DP3CR register, which controls output</DIV>
<DIV>and serial mode selection of the usb port3.</DIV>
<DIV></DIV>
<DIV>></DIV>
<DIV>></DIV>
<DIV>> However, The USB port 3 does not work.</DIV>
<DIV>> Here is the log:</DIV>
<DIV>></DIV>

<DIV>> ======================================</DIV>
<DIV>></DIV>
<DIV>></DIV>
<DIV>> Then I found a bit in UP2OCR -- (VPMBlockEnbN).</DIV>
<DIV>> It is quite strange (if not ugly:( ) the this bit is to control port 3</DIV>
<DIV>> (In UP2OCR--a register for port 2, while there is too many unused bits in </DIV>
<DIV>> UP3OCR)</DIV>
<DIV>></DIV>
<DIV>> But I am not very sure how to use this bit.</DIV>
<DIV>> I grep the source tree, but found nothing about VPMBlockEnbN.</DIV>
<DIV>></DIV>
<DIV>></DIV>
<DIV>> Can anyone tell me that how to write a driver for USB-host-port-3?</DIV>
<DIV>> </DIV>
<DIV></DIV>
<DIV>As far as I know pxa310 usb port3 does not need any special driver</DIV>
<DIV>to work in host mode, ohci-pxa27x is enough.</DIV>
<DIV>Currently, the setup of registers, which are not related to UHC</DIV>
<DIV>(UP2OCR, UP3OCR, etc.), is done in the board code, in the ohci</DIV>
<DIV>callback.</DIV>
<DIV></DIV>
<DIV>> High appreciation for your kind help!</DIV>
