CF-30 USB ports

Ok, I have a USB 2.0 flash drive...
Sometimes my 30 detects it as 1.0 and seems slower than dirt, other times when I boot it says 2.0 and accesses it normally..

What gives?

 

I have had this problem once on the side USB but since I use my rear one now never came up again. Not sure why.

 

Do you have other USB devices plugged in?

 

Latest drivers? Bios?

 

I see it once and a while , depending on which toughbook I am using
No usb1 warning , but a noticable slowdown on transfer speed (most likely running usb 1)
Chipset drivers perhaps ,or the intel mass storage controller software

 

Latest BIOS and I also see it when I have the drive plugged into a verified USB 2.0 HUB.
It also happens on occasion plugged in on its own.
You will usually see how its detected either usb 1 or 2 when your BIOS checks are running before you r OS even attempts to load.

 

Could it be one of those fake / doctored flash drives?

 

Negative....
Does it on my IRONKEY, my OCZ, my Patriot and my MUSHKIN.
Also, if I plug in a USB 2.0 it does the same thing, only detects devices as 1.0.
Getting really annoying..
I've tried different hubs.

Anyone else with a 30 that does this?

 

Really?? Nobody has anything??

 

What chipset does the usb controller use? Maybe try the mfg's website( NEC, VIA?) for newer drivers. My best guess is a driver issue.
I recently installed a pcmcia usb card in my CF29. The motherboard has VIA chipset and the pcmcia has NEC or the other way around. They did not play well together. Wouldn't boot or when it would, it had funky things going on. I pulled the pcmcia and all is better.

 

I cut and pasted this from another forum........

Installing USB 2.0 drivers in Windows ME/2000/XP
 Windows will find a �PCI Universal Serial Bus�. Select �Specify the location of the driver�. Click �Next�.
 In the next window put a check mark in the box next to �Specify Location�. Then click �Browse�.
 Navigate to the folder that contains the USB 2.0 drivers. Click �Next�.

 The driver will be �NEC PCI to USB Enhanced Host Controller�. On the next screen, click �Next�.
 The next dialog will let you know the driver has completed loading. Click �Finish� to finalize the installation.
 A �System Settings Change� dialog may appear, suggesting you �Restart your computer now�.


Finalizing USB 2.0 Hi-Speed hardware settings
USB 2.0 Hi-Speed products that use an NEC chipset have 3 USB host controller engines on board. Two of the host controller engines handle USB 1.1 transactions. One of the host controllers engines handle, USB 2.0 transactions.

USB data traffic is automatically routed to the proper host controller engine depending on the speed of the device that is plugged into the USB 2.0 port. This essentially creates 3 concurrent USB buses. These USB buses allow devices to run in a less congested traffic environment. This
helps devices such as color printers, scanners, video cameras and mass storage devices, which require a high bandwidth, to work well together.

The NEC PCI to USB Enhanced Host Controller driver handles USB 2.0 Hi-Speed (480 Mbits/s) traffic. The two NEC PCI to USB Open Host Controllers handle Full-Speed (12 Mb/s) and Low-Speed (1.5 Mb/s) traffic.

Check your Windows System/Device Manager to confirm proper installation of USB 2.0 Hi-Speed drivers:

NEC PCI to USB Enhanced Host Controller
NEC PCI to USB Open Host Controller
NEC PCI to USB Open Host Controller
USB Root Hub
USB Root Hub"




Check USB controller settings, some default to "Full Speed" (12Mbps)
instead of "High Speed" (480Mbps)

 

That's fine and great once you are in windows...
But when your BIOS detects it as USB 1, and its obvious that its also running at USB 1 when booting from a flash or accessing it in linux, then its another problem all together.

 

Is usb legacy support turned on in the bios? If so,try disabling it.

 

Just tried it, if you disable it, you will not have the option to bot from USB AT ALL.
It will NOT detect the flash drives at boot....
I'll have to try it and see what windows and linux does with that disabled...
