I am now using a customized DM357 board and MV 5.0 with Linux kurnel 2.6.18.
I am now facing a problem:
We extend the USB port of DM357 using a USB HUB.
1) If two USB network cards are connected to the HUB at the same time, they all work well.
2) If two USB hard device are connected to the HUB at the same time, they also all work well.
However, when one USB network card and one USB hard device are connected at the same time to the USB HUB then I have problem. Firstly the USB hard device is mounted in mmt\hd,
if the network card is not actived, then the USB hard device works ok. However, once "ifconfig up" is done for the network card, then "ls" is used
in the directory of mmt\hd, the error occurs as ERROR1 shown in the follows. If the MV5 USB-patch (pro50-0001 - pro50-2318. ) is used, in the stage 3,
new errors occur as shown in the following ERROR 2.
Any help will be appreciated!! Thank you!
