Sorry if you've received this twice - I've resent this message as I think the first one went into write-only memory.
I have a Transend Flash Drive that is presenting problems with later Linux kernels.
The device operates perfectly under the kernel distributed with RedHat8.0 (2.4.18-14) but has problems with all later kernels - including the one in RH9.0 (2.4.20-8). In the past I have installed RH9.0 and run into this problem and I have reverted to RH8.0 so the information below is obtained from a "roll-your-own" version of the 2.4.22 kernel.
The problem is one of _very_ slow throughput to the device - up to 10 seconds to get output from an ls -l /mnt/flash. I suspect that this may, in some way, be connected with the fact the the drive is not recognised at boot time.
I have tried both UHCI drivers. With the usb-uhci driver the USB buses are recognised at boot time but the Flash Drive is not. With the uchi driver, the USB buses are _not_ recognised at boot time - however manually loading the modules overcomes this. With _both_ drivers, the slow throughput problem is evident.
NOTE: This problem _only_ occurs on a Dell Optiplex GX240 system I use at work. My system at home (not a Dell) has no problems with any kernel revision - up to, and including, 2.6.0-test5-mm4. Neither does the problem occur on an older Dell Optiplex GX110 - running vanilla RH9.0.
All the following information was taken from the 2.4.22 system:
