Unknown USB Device Lifebook U772

Postby dvreede » Wed Nov 14, 2012 12:52

Hello all,

My new beautiful Lifebook U772 gives an error message in computer hardware section in Windows 7 Professional.
It does not recognize a USB device. Since no harware is accached to this machine, it must be an internal device.
I have addes a screenshot as an attachment. Which USB device am i Missing?

Thank you for helping me out!

Danny

Maybe knowing the details of the hardware-id could be helpful...

Double-click over unknown-device -> Details, the hardware-id should be
something like Usb\Vid_xxx&Pid_yyyy; having this with google is usually
simple to understand.



Hope this help, ciao
Stefano

Dear Stefano,

Thank you for your help. Unfortunately there is no Unique hardware id is there. Which Advanced Information Field could give us a clue?

Thanks Danny

Really I have no idea, USB\UNKNOWN is a little too anonymous string-id to be helpful :?

Well, generally internal usb components are often related to bluetooth and / or security (TPM etc.), and I know that your model have some sort of particular usb charging option for external devices controlled by a little applet... may be something like that?


Sorry, ciao
Stefano

After contacting Fujitsu Support, the missing USB device turns out to be the Sierra Wireless UMTS card.
All correct drivers were installed, but the UMTS card was still not recognized.
Now Lifebook must be returned to Fujitsu to replace the bad UMTS card.
Thank you for your help.

Hi, how about your case? Is it closed already? Have you received brand new notebook or your device was repaired. Was UMTS card replaced or just some firmware updated.

We bought U772 to our company. And we have exactly the same problem Sierra WWAN sometimes is available to system and sometimes it is "recognized" as UNKNOWN DEVICE. Our notebook is brand new - out of the box and I'm not sure if to contact support and replace whole notebook or just to do some updates by myself.
