af9015 problem on fedora rawhide 9.93 with 2.6.27x kernel

Hi List,

since fedora use 2.6.27 kernels this
is all what happens when i plug in the stick:

Nov 11 13:24:56 thomas-lt kernel: usb 2-6: new high speed USB device using ehci_hcd and address 3
Nov 11 13:24:57 thomas-lt kernel: usb 2-6: configuration #1 chosen from 1 choice

if the stick is connected at boot time everything is working correctly.

can someone please give me a hint where to look for the problem?

version is af9015-e0e0e4ee5b33

I think good place
to test fix is add some sleep (msleep(100)) before/after RECONNECT_USB -command around line 685 in af9015.c file.

you are not alone with this problem. It only happens 2.6.27 kernels. Looks like it does not reconnect device in the USB-bus as it should. I don't have access to 2.6.27 kernel yet, so I cannot examine it more. Hopefully there is someone who could fix that soon... I think good place to test fix is add some sleep (msleep(100)) before/after RECONNECT_USB -command around line 685 in af9015.c file. The other solution could be to remove whole RECONNECT_USB (after firmware download) and set no_reconnect -flag.
