Question about Computers & Internet

1 Answer

I have a Toshiba Equium a100 that wouldn't recognise any usb2 devices. So i deleted all the usb controllers and hubs etc, downloaded the uptodate chipset drivers from Intel and expected the computer to recognise that it needed drivers for USB but I just have the dreaded yellow markers in device manager. Any simple ideas to get the USB working again?

I an not have driver usb for hdd2193 for fix problem


click start control panel administrive tools computer management device manager scroll down universal serial bus controllers you could see a yellow question / exclamation mark? ! or a red X

you will need to update/reinstall drivers

right click to reinstall drivers

if you can see your usb drive but its not working

check the USB leads that attach to the motherboard usually red white green black make sure they are securely seated and have no dust build up on them dust will cause static and a lot of unforeseen problems for a computer and its parts

if you dont have a motherboard disk you will need to download the drivers

Does a Toshiba Equium A200 have a built in microphone?


Here are two different spec sheets for the A200-1V0 & A200-196. Neither one lists a "built-in mic" but both support external mics via 3/8 jack. Also there's always the possibility of using a USB mic.
A200-1V0
A200-196
Hope this helps, if so please comment, vote, etc.
Thank you.

USB Port Speeds


Usually it's best to consult manufacturer's info on your computer. If not available, you can check it by going to start menu>settings>control panel>system>device manager and then look for "universal serial bus controllers" - several devices should be visible here and if you have USB2 it will be clearly stated (e.g. something along the lines of "USB2 Enhanced Host Controller").
Generally I would say if your computer is less than 4-5 years old, it will probably have USB2.
Hope this helps,
Raf

Drive not recognised


Sounds like a possible problem with the usb ports. Does the usb drive work on other pc's? If so, does your laptop recognize other usb devices (flash drives, mouse, keyboard etc.)?

If your laptop won't recognize other usb devices all the time, try this: go into device manager, go to the bottom, expand 'universal serial bus controllers'. Starting at the bottom of the list, right click on each item and left-click 'delete'. At some point you will likely lose your mouse/tochpad as it is probably an internal usb device. If this happens, press the power button on the laptop once to shut it down. Restart it, and windows will re-detect the deleted usb hubs and hopefully fix the problem. If this doesn't do it, go back and delete the other usb root hubs and host controllers. This is totally safe for your system and often fixes this issue. Windows will always re-detect hardware at boot time.

let me know if this helps or not :)

To reinstall USB drivers, you need to reinstall the system, as USB root hub drivers are built in on Windows.

Tray first removing laptop battery and unplugging AC charger for ten or fifteen minutes, this will get rid of static charges that can cause USB not to work.

If that does not solve the problem then you need to reinstall Windows. Try a system restore first.
