Hi All,
I found a serious issue when I used usb hub with inserting WIFI device zydas
1211b based WIFI dongle and usb storage disk.
1. During starting the linux kernel, I got many error messages
"FAT: Filesystem panic (dev sda1)
fat_get_cluster: invalid cluster chain (i_pos 0)
ls: /usb/merge: Input/output error "
2. After finishing the linux kernel boot, I loaded the wifi device driver
module (insmod zd1211b.ko) and wifi device can work.
When I did bandwidth test using IPERF(bandwidth test tool), frequently I
got errors :
"Tx status: -110, Error Occur in zd1211_rx_comp_cb, nonzero read bulk status
received: -EPROTO", and usb storage disk can not be written (it was set as
read-only filesystem).
Your much help is appreciated. Thanks in advance.
Best Regards,
Jeff
