Hello group.

I have Samsung SyncMaster 957MB monitor which has a USB control feature
(for adjusting geometry, brightness, contrast, etc.)
The problem is that this thing (USB) doesn't work on my WinXP. I've tried
everything, got new BIOS, WinXP service pack 1a, all of the updates. I've
tried it on each USB port - same result - doesn't work. I get "Unknown
device" baloon, then "Device is installed..." baloon, but after few seconds
"Device has malfunctioned..., etc.", and the picture control funcionality
doesn't work (Picture control software (MouScreen) says that "No USB
Monitor is attached").

I know that USB ports on my computer are working fine, because I've got a
USB scanner, FlashDrive, Joystick, and all of them are working fine. I've
also tried my monitor's USB controls on a friend's computer to make sure
that the monitor's USB device is working. It worked fine. (He also has
WinXP, but without SP1)

Does someone know what the problem might be?

I have:
MSI k7n266pro with nForce chipset, USB 1.1
Athlon XP 1600+
512MB 266MHz DDR RAM

WinXP Pro 5.1.2600 SP1 2600
USB controller is Standard OpenHCD USB Host Controller

No USB keyboard or mouse, only PS/2;
No external USB hubs.

Reinstalling Windows doesn't help.

TNX for reading this, and I hope someone has the answer. :)

Cheerio!

I'm not sure if I understand the question but...... do you have the USB drive mapped already? Windows XP maps USB keys to F: If it is already in use by another folder you can't always access the USB drive.
 
I'm lost on this USB device that is mentioned

I've gone to Samsung's webpage for the monitor and can not find any info on a USB device
Mouscreen is a software application that uses a mouse to change settings, instead of using the monitors buttons

Is the USB device for a wireless mouse, which isn't working or is it MouScreen that doesn't work
Is MouScreen installed on the computer from the cd diskette that come with the monitor

Please clearify you question

Thanx. I've also been to Samsung's webpage. I also haven't find any help or
support for monitor's USB devices. I guess this things doesn't happen
normally. Except in my case. :) (even in manual, recomendation for solving
this problem is to unplug and then reconnect USB cable, which, of course
doesn't help)

At first, TNX for replying.
I'm sorry, my question was a bit blurry, I can admit that. :)
(English is not my native language, and I was a bit tired when I was
writing the post...)

This is the thing. My monitor came with the USB connector (for changing
settings via software, rather than monitor buttons), along the classic
analogue D-sub connector (for picture). The problem is in the USB
component. MouScreen is working fine, because i've installed it on a
friend's computer and used it to control my monitor.

However, when I connect monitor's USB to my computer (with same cable which
I've used when connecting to a friend's computer), the Windows says that
"USB device is not recognized" and in Device Manager I have "Unknown
device". On a friend's computer it's not "unknown device". Windows
recognize it as a Human Interface Device, and I can control the picture
with MouScreen there.

The logical conclusion would be that something is wrong with my root USB
hub, but that is not true, because all other USB devices that I have (USB
thumbdrive, USB scanner, USB joystick) are working properly, so I cannot
put a blame directly on USB ports on my comp.

I've searched the web insanely, and did not find any clue whatsoever. I've
tried everything (been through the troubleshooter, and did all the steps,
flashed BIOS with newest version of it, reinstalled Windows) but I simply
cannot make Windows to recognize it.

I'm sorry if I made some major grammatical mistakes in this post which
could lead to misunderstanding. But, unfortunately, English is not my
native language, and I don't use it very often. So, my appologies to you
all...

TNX one again, and I would be very grateful if you could give me some clue
of what could be wrong here. Some WinXP patch maybe - I did'n find any that
would solve this.

Cheerio!
