still more USB flashdrive problems...

Lord Zoltar · 01-13-2005, 09:03 PM

Still having trouble with the USB flashdrive thing. I got the biggest problems sorted out already, so I can now mount the drive and read the files on it, but I'm still having a few problems.
(older thread)
1) I cannot use the USB flash drive with all the USB ports. It seems only the ones on the back of the case are working. The two in front cause errors (see the other thread for details). Also, I've noticed that with one of the USB ports (the one right beside the mouse port), plugging the USB flashdrive causes the whole system to lock up completely. mouse, keyboard, everything! have to force a reboot to fix it. I am at a total loss to explain this, since I can use my USB printer with the two USB ports on the front of my case. Whatever, at leat I can access the drive through one port.
2) I cannot write to the USB flashdrive. I have this:

Code:

/dev/hda5        swap             swap        defaults         0   0
/dev/hda3        /                ext3        defaults         1   1
/dev/cdrom       /mnt/cdrom       iso9660     noauto,owner,ro,user  0   0
/dev/fd0         /mnt/floppy      auto        noauto,owner,user     0   0
devpts           /dev/pts         devpts      gid=5,mode=620   0   0
/dev/sda1       /mnt/USBflashdrive      auto    noauto,owner,ro,user    0     0



proc             /proc            proc        defaults         0   0

in my /etc/fstab file. the line for the USBflashdrive is just copied from what I did for the floppy drive. I figured that since they're both read-write removable media, it should be similar, just change the mount folder.

I also have

Code:

# disk devices
hd*:root:disk:660
sd*:root:disk:666
dasd*:root:disk:660
ataraid*:root:disk:660
loop*:root:disk:660
md*:root:disk:660
ide/*/*/*/*/*:root:disk:660
discs/*/*:root:disk:660
loop/*:root:disk:660
md/*:root:disk:660

in my udev.permissions file. so /dev/sd* should have read-write access for all, and it does. the problem is with /mnt/USBflash, which does NOT have write access for anyone, and the problem is:
I can't chmod write access onto it!

Code:

/mnt# chmod a+w USBflashdrive
chmod: changing permissions of `USBflashdrive': Read-only file system

Why is the USBflashdrive a read-only filesystem? OSX and WinXP were both able to read and write to it with no problems.

shouldnt your line:
/dev/sda1 /mnt/USBflashdrive auto noauto,owner,ro,user 0 0
be:
/dev/sda1 /mnt/USBflashdrive auto noauto,owner,rw,user 0 0

edit: i used an arrow to point out the change i made, but it didnt work as planned ;p... but notice the "rw" not "ro"

so that sets "read/write" permission.. not "read-only"?

Lord Zoltar · 01-13-2005, 09:23 PM

/blushes...
yes, that SHOULD be rw... ok i think i copied from the cdrom line instead. no more of this 3a.m. system tweeking...

nadroj · 01-13-2005, 09:27 PM

so your set now?
time to help ME now!

Lord Zoltar · 01-13-2005, 09:57 PM

lol! I still haven't solved the mysterious USB ports that crash/don't work...

A power issue? The USB printer has its own juice. Try some other unpowreed USB devices.

Lord Zoltar · 01-21-2005, 05:11 PM

I have no other unpowered USB device.

install ACPI and make sure the kernel has ACPI support

Lord Zoltar · 01-22-2005, 12:38 PM

Code:

modprobe acpi
FATAL: Error inserting acpi_cpufreq (/lib/modules/2.6.10/kernel/arch/i386/kernel/cpu/cpufreq/acpi-cpufreq.ko): No such device

hmm....
acpi-cpufreq.ko... is that related to the acpi option for cpu frequency scaling? If so, is it experimental? with the message "if uncertain, say no"? If so, that's probably why I didn't compile that option. I tend to compile any kernel option/module that looks useful, except the ones that say they are experimental/potentialy harmful. oh well... hey, is there anyway to compile that module without a whole new kernel recompile?
