1 This is really making me puzzle:
2 sappho ~ # lspci | grep USB
3 0000:02:02.0 USB Controller: NEC Corporation USB (rev 41)
4 0000:02:02.1 USB Controller: NEC Corporation USB (rev 41)
5 0000:02:02.2 USB Controller: NEC Corporation USB 2.0 (rev 02)
6
7 When the kernel boots it shows me that only ohci device is discovered,
8 someone suggested that ohci only support USB 1.x. Now lspci shows the
9 card has "USB 2.0". I don't understand, does it work in the way that the
10 card either work in 2.0 mode with one device, or USB 1.0 with two
11 separate devices?
12
13 What if I remove OCHI and add back only UHCI driver in the kernel?
