USB issue Windows7Ult64bit_HPxw4400

I cannot use the "newer" usb devices on pc HPXW4400 info here http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c00775230
After connecting the flashdrive (Kingston DataTravelerSE9 8GB) or writing tablets Genius G-Pen F610 although the OS appears, but does not find the driver on win update. Then, these devices are seen as unknown in the device manager (yellow triangle). I tried a different physical usb controller, with the same result. Other devices via usb (older flashdrives, cameras, external hdd) operate normally. On another pc (winxp) operate these new devices too. I tried to find an update for HP motherboard (type 0A68h, chipset i975x), without success. The problem is the timeliness of official support for HP, where the last update chipset is 6 years old ...
Does anyone have similar experiences with Windows7? Or what you can do in this situation? Return to XP is the last option.
thanks for the help
