Should 'kernel polling' be enabled to auto-mount USB drives

Hello
1. On one of the machines that I installed Salix XFCE 14.1, USB pen drives, ADATA external HDD are not being recognized
2. Standard tricks like enabling volume management, ticking the relevant options under 'Removable drives and media' enabling thunar-volman in settings are all done
3. On 'Linux-questions.org', in one of the posts for this problem, I read that 'Kernel polling' should be enabled. Is this true for salix 14.1 xfce?
4. On other four machines that I have installed Salix 14.1, XFCE, including a laptop, I have not enabled kernel polling myself. By default if it is enabled, I am not aware. I have not checked. Pl. some body clarify this.

If there are additional tricks / points wrt enabling the auto-mount of USB drives, pl. share.

The USB drives is not listed under 'devices' in Thunar but always displayed in the terminal with the commamd 'lsusb'

Is this really a fresh installation, with nothing changed, or did you remove things "you did not need"? What other changes have you done to the system?

Run

Code: Select all

sudo tail -f /var/log/messages
and then plug in a drive that doesn't work. Post what comes out.

No internet connection on that machine. As usual, wvdial yet to be installed, no network manager, sakis3g not working. If usb drives are recognized, I would have loaded wvdials

This looks like a hardware problem. Try booting with the additional kernel option:

Code: Select all

usb-storage.delay_use=5
See if that makes any difference.

Your Adata USB drive (Model MV611) is USB 3,0 so you may want to try plugging it into a USB 3.0 port if the computer has one.
