Tool/software: Linux
Hi Sirs,
We are using DM385 custom board with IPNC 3.8.We tried to enable the usb host((ohci-hcd) and usb serial driver(option,usb_wwan,usbserial) in the kernel then we inserted the usb device to test.But It did not seem to be successful.
1.I can not see the informations of USB device in /proc/tty/usb
2.I can not see the major number and minor number in /sys/dev/char
3.But I can see the character device (188 ttyUSB) in /proc/devices
4.The messages in the kernel are as below.It seem the driver can be enabled.
