I have some serious problems with Technaxx pci-e 302p card. It has uPD720200a NEC chip with 4020 firmware. BIOS recognises it. Sometimes it recognises devices and system mounts them and are functional for few minutes, other times they can't be mount and error occours. After fresh install card worked fine, but after kernel and firmware update it behaves as mentioned.

Are there any other outputs need for answering? I'll post them ASAP.

I could of course reject updating the system but I think it's halfway solution. Any help appreciated. BTW USB 2.0 and 1.1 ports run well, card itself runs under win7 as charm.

I had the same issue with my USB 3.0 card which uses Nec/Renesis controller. My card has two ports and when I connected storage enclosure (WD) to one port I had problems with recognizing it.

What I found - I had to plug some other device into the second port to make the first port work. Apparently kernel driver for Nec chips cannot selectively enable/disable individual ports in my card. So I needed to use BOTH ports on that card to make it work correctly.

I just plugged in webcam, but I think any other usb device will do the job. Ports are completely independent (they are seen as separate USB buses in "lsusb -t" output), so if one device is slow, it won't affect transfer speed of another port.
