[問題] Red Hat 9不支援USB2.0嗎?
我想問一下
Red hat 9 的kernel是2.4.20,
我查了一下,
有個資料寫:
LinuxR USB 2.0 driver
Linux USB 2.0 driver is supported from kernel 2.4.19 or later. Kernel is
updated regularly, and the problems in older version may be solved in the
latest kernel. So it is desirable to use the latest one. The following URL is
for your reference.
http://www.linux-usb.org
那麼意思是說,照道理,2.4.19以後應該要支援usb 2.0吧
可是我在red hat 9(2.4.20smp)之下,卻只能用usb 1.1 @@?
我插上usb 2.0的usb driver就會出現一連串的
"_usb_control/bulk_msg:timeout"
我想問一下,red hat 9有沒有支援usb 2.0呢?
然後它還有一句話,
For Kernel 2.4.26 patch, refer to this page.
所以我就去找了那個page,page 如下,
是不是指說要2.4.22以後才能支援到usb 2.0呢?
麻煩版上大大不吝指點一二,
感恩,謝謝喔!

Linux and USB 2.0
Last Update: 29 November 2004
This is a short writeup explaining what USB 2.0 changed and what's going on
with it in Linux. It starts by talking about user visible changes (including
usbfs information) followed by driver-visible ones. Finally it summarizes the
current state of Linux USB 2.0 driver support in recent 2.4 and 2.6 kernels.
If you want assistance getting this working on your hardware, try the
linux-usb-users (or linux-usb-devel) mailing lists at
http://www.linux-usb.org.
If you're a 2.4 user, use 2.4.22 or newer kernels. Newer kernels (including
2.6.x ones) have updates which seem to resolve the worst problems reported.
The driver version string should be no older than June 2003. (VT6202 problems
may still remain, especially on 2.4 kernels.)
Some older Linux distributions ship 2.4.18 kernels with EHCI code based on
much older code, similar to what was in 2.5.2; the newer code supports more
hardware, fixes bugs, is smaller, and has other goodness. If you're building
a distribution, avoid using such old code; in particular, 2.4 versions of the
EHCI driver are no longer being kept current.
