OK. All of a sudden my USB mouse stopped working. I tried a different port but Windows would still give me "USB device not recognized" message. I Googled the issue and it appears that this problem is known and there's a fix that involves removing a couple of INF files/etc. (http://kenno.wordpress.com/2008/01/2...ize-usb-drive/ for instance). That did not help. At the same time, my USB hard drive works fine. Windows also registers the action of inserting the mouse.
I tried booting Windows (Vista 64) installation from DVD and the mouse didn't work there as well, although it always works once you're presented with a menu. I then formatted my parition, did a clean install... and... same thing. USB ports don't recognize my 2 mice (Microsoft and Logitech).
Moreover, after installing all drivers/etc., my bult-in webcam and fingerprint reader don't work. The latter asks to connect the device to USB. Odd, since it's built-in It says "biometric device" is not detected.
This is the weirdest problem I've ever seen. Definitely not a problem with my devices nor is it a Windows problem. It appears that USB ports are, uhm, "half dead". How's that possible?
happened to me twice on my SR290. Seems to be a Vista issue. First time the problem solved by itself (I think i did the INF file replacement thing). Second time, nothing worked. I finally had to do a full format of C drive and re-install. The whole things sucked.
It's definitely not a Vista issue (although Vista does have a problem of similar nature), since USB ports don't work under Windows and Linux, including Windows Vista installation screen where they ALWAYS work. Completely removing the partition, formatting it, installing a clean copy of Windows doesn't help. Today I also tried GPARTED (parition management software on bootable CD that's based on Linux and where I know the USB mouse works on every computer, including this one when I first used it to remove Sony's hidden partition)... and still nothing. Not wasting any more time. Sending it back.
ain't vista or xp problem. most vaios have shared ports and they are underpowered. my T was 'loosing' the usb powered scanner if I have WiFi/BT on. My TZ would reset the USB bridge on the left when an external USB powered 7200RPM drive is connected (all those become either UNKNOWN or USB DEVICE with no specificity). The only remedy i was able to find is to COMPLETELY shut down the machine. Take the battery for 10 sec and reconnect it. All that was sporadic, not always the same results i.e. sometimes I went without this quirk for a month or so.
Please remember, Old HPs, VAIO and some Dells will not reset the device state UNTIL you take the battery out for 10 seconds or more. There is always power going through it. That's why your VAIO will fully drain a battery even on 'shutdown' after a few days while not being connected to the A/C
Most VAIOS have the following on the USB BUS:
PCI-E MiniCard Bridge -> USB for Wireless & WWAN
Some Have the TouchPad as well.
You see where the whole s&it comes from, right?!

Thank you so much. I wasted a couple of hours researching on Sony's support site and chatting with their support people and nothing worked. Two minutes of my time on this site and I found my solution. Taking the battery out worked like a charm. Thanks again.
Too bad not everyone listens carefully when I talk and render opinion/suggest solutions. I've been there and done that (most of my posts are based on experience and I deal with hardware on a daily basis).
Either way. I believe there should be a sticky on each forum / make on how to deal with stupid issues, like this clear Sony design flaw or how to deal with the buggy XP/Vista drivers for BootCamp that cause the rigs to completely lock up, etc. It will save a lot of time for people to search around for a solution that shouldn't have been there to begin with.
I am dissapointed to say i have the exact same problem with my AW120 J/H that i just bought. I was most annoyed to find out everything worked when i took it back to the store (i had the battery out).
It is good to know that there is a solution to this problem but i am so dissapointed that i have to constantly manage my laptop with a shutdown and battery removal. I think this is grounds for a return and purchase of a new model.
