Not having the right Video drivers means your monitor and video runs poorly.
You must have suitable drivers for your monitor, video graphics card, VGA, and operating system to give you the performance you deserve Your computer USB port doesn't recognize attached devices and gives you Driver Error.
However, these devices will not just produce sound because they are connected to your PC, a matching AUDIO DRIVER must be installed for your sound card to work properly.
But the U7, at least, has been plagued by USB failures at around the one year mark. Solid construction, all metal case, excellent drivers and easy setup, although the instruction manual is not very useful. It is inexpensive and has a great warranty (on paper, anyway). They are a little cheaper than the Asus USB cards if you prefer an internal card. The best choices here are the Asus Xonar DSX PCIe and the M-Audio Audiophile 2496 PCI. An amazing value is the little Syba (VIA) SD-AUD20101 USB sound card for $12. It could be handy for somwthing like Field Day operation.
It is unclear what the failure mode is (hardware, firmware or driver), but ASUS will replace the card with no questions asked up to one year. I recently tested a Behringer UMC202HD USB sound card. The signals fall off about 10 d B compared to the center once you get out to 190 k Hz, but it's pretty flat up to that point varying by about an S-Unit most of the way. It can only be used with programs which allow for sample offsets between channels, like Na P3, CW Skimmer and HDSDR.
A good number of laptop or computer hardware are interconnected with other segments, drivers and devices and therefore are predisposed to corruption prompted by almost any particular expired driver they get in touch with.
Take into account that the need for you to be familiar with specific label of each driver you are interested in installing is totally unnecessary and any time it comes to employing an automated scanner that accomplishes it all for you and needs zero direction or configuration on your behalf.
A High Definition Audio device can reside on an internal audio card, or the device can be part of an integrated motherboard chip set.
