Easy USB question

Can a motherboard which is USB 1.1 compliant easily become USB 2.0 compliant by flashing the bios? Is there any other technical difference?

Secondly, if the main motherboard is 1.1 USB compliant and I add a PCI USB 2.0 card to the system, will those PCI/USB ports be 2.0 compliant despite the main system being 1.1? In other words, can I benefit from the higher speeds that 2.0 offers whilst leaving my original system as it is?

short ans is NO
Yes u can update the BIOS check with your Hardware manufacturer if they have it.

Second question answer No
You cannot convert a USB 1.1 motherboard by flashing its BIOS to an updated version because the hardware was meant only for USB 1.1 and no software BIOS fix is possible for it to be converted to USB 2.0.

Uhm, if you install a PCI USB 2.0 card, it wont affect the USB 1.1 ports that you have on your motherboard. In other words the USB 1.1 is still USB 1.1 and the PCI USB 2.0 is PCI USB 2.0, but you can attach USB 1.1 devices to your PCI USB 2.0 ports since it is backwards compatible with USB 1.1.

Like what kiranghag said, short answer is no... sorry...
What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

shijirou, your response appears to be the same as PC World when I spoke to them just now.

So, if I attach a new PCI 2.0 USB card, then I just want to confirm, that any USB 2.0 device that I then plug into THE CARD, should then work at 480bits speed and not as slow as the 1.1 spec?
Your card may have two or three USB controllers. You must install USB 2.0 devices under the same controller. If you install 1.1 and 2.0 devices under the same controller, the speed will down to 1.1.

ey143: Yes that's pretty much it but take into consideration what hpman820129 said.
