7340 + phoenix (card reader) = panic in 5s

[avathar]

Hello,
i'm trying to run card reader phoenix usb (3,57-6MHz ver.7.6) on my 7340.
I use this reader on my 7240 without any problem. Below i include some logs from 7240 & 7340, maybe someone can tell me something based on these logs.

Reader is attached with this command:
modprobe ftdi_sio vendor=0x403 product=0x6001

7240:

I remember i tryed such cardreader on my 7390er with the .22 - Firmware. I got a /dev/ttyUSB0 but when i started a application (name of this application beginns with "OS") then fritzbox rebooted. With the new labor-firmware or 05.50 - Firmware i do not have this Problem anymore. At the moment the cardreader works fine with a beta-Firmware in a 7320er Fritzbox.

Maybe this post will help you.

Thanks for information.
I think that i found the source of problem. I recompiled kernel module ftdi_sio.ko and now this driver is in version 1.5.0
So far so good. So likely driver in version 1.4.3 wasn't working properly.

I forget to write, that my experiments were without freetz. It works fine with the last original-avm-firmware.
