I spent about 8 hours yesterday trying everything I could think of and every solution I could find on the internet, I still do not have the n-trig win 64bit update working correctly.
I do however have rudimentary touchscreen function which I know many of you do not, [b]I will try and guide you to get from "Unknown usb device" to getting some touchscreen function back[/b] untill an actual solution turns up
Firstly make sure your bios is up to date f.21 being the newest you can get that here http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=ob-7482...
Next flash your laptop manually by turning off the machine then holding the power button in the on position till the laptop turns on and off again. (installing the bios update will do this for you, the first time)
When you turn the system on again go to control panel> device manager now hopefully you should see digitizer with 3 entries (if you tried to install the 2.59 update anyway).
Install the 2.148 rev A n-trig package which was kindly found by zor here http://www.touchsmartdevzone.com/forum/thread/1985/Official-HP-N-Trig-driver-... . Now you may strike lucky here and this goes solves your problem but if your like me this will also give you a fatal error blah blah.
Restart the laptop, back to device manager you will either have Unknown usb device again or digitizer with 1 entry and 2 new entries under Human Interface devices. IF YOU HAVE THE DIGITIZER PLUS 2 ENTRIES IN HID STOP HERE, SHUTDOWN YOUR MACHINE AND TURN IT BACK ON TOUCHSCREEN SCHOULD BE WORKING AGAIN.
If unknown usb device has reared its ugly head again go ahead and flash again. When you restart back to device manager see if the digitizer + hid entries are now there. If they are shutdown the computer and turn it back on again rudimentary touchscreen function should have returned.
PLEASE ONLY TRY THIS IF YOUR STUCK WITH "UNKNOWN USB DEVICE" IN DEVICE MANAGER AND YOUR DESPERATE
Now I can't confirm if this works right, all I know is this was the process I used that gEt back my touchscreen capabilities. From what I can tell I have some broken n-trig drivers but no firmware (no n-trig settings icon shows up in control panel)
I can't stress this enough you try this at your own risk I will not be held accountable.
Oh, and if anyone else has found a way to actually get their touchscreen completely working again from "unknown device" please do tell
So you claim that the bios flash and then the reset via holding the power button clears the firmware for the digitizer controller?

I haven't the faintest idea what it does, I only know it worked for me :)
I tried installing either software bundle, after a restart i'd be back to square one "unknown usb controller" but everytime a hard reset would result in the n-trig device driver showing up again in device manager. Sorry I can't be more specific but it took from 730pm till 330am to get where I am now, I was foaming at the mouth with anger by then so hopefully I remembered the process correctly.
short answer: yes, n-trig device drivers are installed but I have no firmware (which seems to be the root of all these problems)
I am desperate so I will try this as soon as I get home!
-Currently Win7 default drivers give me single touch which is the best I get..
-The 2.59 give me a 1/10 chance of response after touching, pen works though.
-The unofficial "Best Buy" drivers resulted in clicks in upper right corner wherever I clicked.
-The new official 64-bit Win7 drivers made both touch and pen disabled, and now after a few retries I get the "fatal error" when I attempt to install.
Anyone recognize these symptoms? I have a tx2-1270us
I will report back when I have any results.
With rudimentary Touch support, do you mean single-touch only? Or did you get multi-touch?
I did this but all I get is single-touch. I lost the multi-touch function.
Anyone got a fix?
EDIT: so I uninstalled that one and installed the one on the n-trig site. I now can use 2 fingers, but not like before when I could use up to 5.
Anyone help me?
The drivers from N-trigs site are limited to 2 point touch on purpose (latest release they have, not the old RC release ones)

I would suggest you un-install all touchscreen software with windows 7. All the drivers right now are currently broken. The pen functionality works way better with 7's native drivers than any of the updated drivers although you only have single touch functionality. For now, patience will be required until they release a driver that actually works.

If you upgrade HP Vista image, Windows 7 installs its own (Microsoft) multi-touch driver that supports 10 points + full pen functionality. But you will have two unknown devices in Device Manager. The RC 2.59 (4 points) from n-trig fixes this issue (if it bothers you) and is also good. Win7 Touchpack works great on the tx2 with 4+ points (but not with two points). It doesn't need PhysX or NVIDIA (but will benefit from them on machines with this hardware), and works fine under the ATI HD 3200 in our tx2 (all touchpack apps work flawlessly).
According to n-trig's own definition 2 points is not true multi-touch: http://www.n-trig.com/Data/Uploads/Misc/N-trig_Paper_on_Multi-Touch_2008.pdf
At least 4 points are needed (and multi-hand), to be able to claim proper multi-touch support.
Ok so I went back to win7s native one but wanted multi-touch.
So I went to the OLD n-trig one. the one that works. the only downside is that the pen button doesn't work as a right click but does on the windows 7 native driver

Everytime I try an updated driver, inking in One Note is horrible; lag, decreased sensitivity, dead spots. I use the pen more than anything for taking notes in school so if pen doesn't work right, it doesn't matter if I have multi-touch.

The Vista n-trig has 10 points and Windows 7 upgrade correctly picks this up during the upgrade, replacing n-trig's Vista driver with Microsoft's own multitouch (10 points) driver.
The vista driver is hardware driven, recognizing only certain gestures, the newer version is supposed to be all software/driver driven.
Ceez said: The vista driver is hardware driven, recognizing only certain gestures, the newer version is supposed to be all software/driver driven.This is unrelated to my post above. The Vista driver is only a "trick" to let Windows 7 install its native 10 point driver, and it works! When updating, Windows 7 reads existing firmware settings then decides (remember n-trig driver is also a firmware update). You end up with a Windows 7 brandnew driver, not any n-trig/Vista driver.
CyrenesFriend said:That sounds great, I'll have to try it. My comment was referring to the firmware, n trig has a paper out about multi touch drivers that explain what I mentioned above.Ceez said: The vista driver is hardware driven, recognizing only certain gestures, the newer version is supposed to be all software/driver driven.This is unrelated to my post above.

I think I broke my windows 7 installation so I'm trying that today. But hey couldn't you just download the Vista drivers and then install them on windows 7 instead of reformatting then doing an upgrade from vista?
