Greetings! Here be a tale or two. Red Hat 9, by the way, on a Compaq Armada 1750 laptop with USB port.
Debian and co. use hotplug which manages the insert events and can automatically mount partitions.
Which kernel are you using?
Regards, Tim.
Well, I's rather not go installing a different version of Linux! Too much hassle given what's on this machine already.
Anyway, I have
/usr/src/linux-2.4.20-8
so I guess it's kernel 2.4.20-8!
What's peculiar is that before I ever connected the Camera to the USB socket, I could plug and unplug the MemStick any number of times and it would work every time. So up till yesterday that kernel has worked fine with the USB stick.
Now, if I plug the stick in as the first USB item after a reboot, the Stick works first time and, once unplugged, thereafter not at all until the next reboot, and the Camera won't work at all.
But if I plug the Camera in as the first USB item after a reboot, the Camera works every time it's plugged in, but the stick never works.
So for some reason, using the Camera for the first time has screwed up something in the Stick usage which was not screwed up before, even if I don't use the Camera at all!
It rather lookas as though it may be the module configuration for the USB/SCSI setup when a USB storage device is plugged in which has got into a twist.
But I'm actually beginning to wonder if plugging in the USB plug on the Camera cable bent something in the USB socket which affects the contact with the USB plug on the Stick, so that unplugging doesn't get properly registered, and plugging doesn't get properly registered to over-ride a previous Camera plugin.
If so, then it could be bad news --nothing nastier to get fixed than a broken USB socket on a laptop!
An alternative is that the Stick plug may be dodgy -- can only test that by trying another stick, I suppose.
Thanks for the suggestion, anyway!
Ted.
