smartcard not detected

smartcard not detected

[Raph]

Hi,
I'm using an eeepc 701 and just bought a SDHC card which
doesn't get detected unless :
- it's plugged at boot time
- I use udevadm trigger
- it has been detected once before (with either the first or
second method above)
If it's not an expected behavior below are some infos.

Thanks

Something on system is supposed to poll the device, otherwise media
changes are not detected. So either HAL or DeviceKit-disks or udisks
usually run and do that. I guess running "touch /dev/sdX" will make
the device appear too. That's what a polling process would do, by
opening the device every couple of seconds.

Oh, and a SDHC card has not much to do with a smartcard like mentioned
in the Subject:. :)

right, memory card is the word.

I must correct my previous email: the device does not shows up ...
in less than 15 seconds, that may be considered as normal but that's
more than other devices I plugged in until now.

But, from my last tests, the real problem seems to be that the device
doesn't get removed from /dev and /sys/block after a physical removal.
That's what wrongly brought me to my 3rd diagnostic in my previous email.
I guess that's related to the card reader driver, so... excuse me for the noise.
