Здравейте

Ползвам упомената в заглавието дистрибуция, с ядро: 3.16.0-4-amd64 и дъно: ASUS M4A88T-USB3.
Ползвам udisks-glue и samba за да си пускам филмчета и други от една USB докинг станция за дискове.
Днес седнах да си прехвърлям филми и ми направи впечатление, че скоростта не е каквато би трябвало да е, а именно:
hdparm -t:

Код:

/dev/sde:
 Timing buffered disk reads: 100 MB in  3.02 seconds =  33.06 MB/sec

което ме наведе на мисълта да проверя какви устройства се виждат:

като ASMedia-та е докинг станцията.

като xhci_hcd съм го заредил принудително аз.

Дънната платка със сигурност има работещо USB 3, тествал съм го под винбозата и работи отлично.

Много ще съм благодарен, ако дадете идея, насока или решение на това как да си подкарам USБ тройката да работи като такава, а не като двойка!

Благодаря предварително!
