Usb hubs not working with my m860tu

Hi! does anyone have any problem regarding usb hubs? when i plug one in, then i plug in the hub any usb device and it starts stuttering all over....:S

 

does the USB hub have an external (AC) power supply? your gadgets might be drawing more juice than the USB port can supply...

 

it doesnt....well i tried a usb hub 1.1 and it worked....but this one isnt working properly but it was working in my laptop from work.........:S

 

i also have a happy hacking keyboard pro 2 which has a usb hub too, when i plug the keyboard in the stuttering starts...:S

 

just got a blue screen after inserting one more devide in the hub....well i give up, all ports are workingly directly with the devices.....ill try a powered hub later.

 

You probably need a powered hub, USB doesn't have the best power output if you know what I mean.

 

im suspicous of the latest bios updates in this regard, the updates reference some correction int ac/dv power, it might have alter the energy output???

Edit: the hub works on my dell computer from work but i assume its different machines so, cant really compare....

 

blue, what power supply do you have? what are its specs?

 

You have a crappy hub. Get a better hub? Yours sounds like it has all the symptoms of a failing/bad model.

 

Need to check it back at home....

 

Ive seen your thread, and i already thought about it....but the thing is i have this great keyboard i use which also happens to have a usb hub and it used to work well, but since i updated the bios(to witch version i dont know) the thing started to work badly, and if i plug anything at the its hub, then it completely stutters and refuses to work well. Im still going to try those y usb cables to see if i can get it to work well. I managed to make it work well trrough a 1.1 usb hub......
Basically all devices that dont seem to have any usb hub work well, even the external 2.0 usb hdd....

 

ah. sorry i think that would be a board problem. my ports are working fine all at the same time.

 

My ports work fine, with the devices...but with the hubs im having trouble. How did you tested yours?

 

Oh, I've misread your problem. Well if your talking about hubs, you would really be expecting a problem. Since hubs divides the drawn current from one usb port to the number of ports in the hub making devices connected to it function improperly. This is a common problem for most hubs that's why some have a power supply unit that comes with them.

 

well just bough a hub that comes with a y cable but it still doesnt work.....it doesnt come with a power supply thought...

 

Bought another usb hub from targus, things still dont work, i mean, all the usb devices keep working well, but as soon as i plug a 2.0 hub, the keyboard or mouse wont work properly....

Edit: well the keyboard which has has a 2 port 2.0 usb hub doesnt work directly connected to the laptop, but now works through a 1.1 usb hub....what the hell???

 

Just got the blue screen with the IRQL_NOT_LESS_OR_EQUAL after plugging a pen in a 2.0 usb hub.....ive read that it might be sp2 problems.....
