Question

求教编译openwrt x86，usb启动不成功

Answer 1

Make kernel_menuconfig

Device Drivers --->
SCSI device support --->

(Although SCSI will be enabled automatically when selecting USB Mass Storage,
we need to enable disk support.)
--- SCSI support type (disk, tape, CD-ROM)
<*> SCSI disk support

(Then move back a level and go into USB support)
USB support --->

(This is the root hub and is required for USB support.
If you'd like to compile this as a module, it will be called usbcore.)
<*> Support for Host-side USB

(Select at least one of the HCDs. If you are unsure, picking all is fine.)
--- USB Host Controller Drivers
<*> EHCI HCD (USB 2.0) support
< > OHCI HCD support
<*> UHCI HCD (most Intel and VIA) support

(Moving a little further down, we come to CDC and mass storage.)
< > USB Modem (CDC ACM) support
<*> USB Printer support
<*> USB Mass Storage support

(If you have a USB Network Card like the RTL8150, you'll need this)
USB Network Adapters --->
<*> USB RTL8150 based ethernet device support (EXPERIMENTAL)

(If you have a serial to USB converter like the Prolific 2303, you'll need this)
USB Serial Converter support --->
<*> USB Serial Converter support
<*> USB Prolific 2303 Single Port Serial Driver (NEW)

选上这些，，，再编译一次固件就可以了。
