我在 310 上可以正常使用 USB HOST PORT 2 (OTG) ,但是使用 USB HOST PORT 3 时,终端输出如下信息
<6>usb 1-3: new full speed USB device using pxa27x-ohci and address 84
usb 1-3: device descriptor read/64, error -62
usb 1-3: device descriptor read/64, error -62
<6>usb 1-3: new full speed USB device using pxa27x-ohci and address 85
usb 1-3: device descriptor read/64, error -62
usb 1-3: device descriptor read/64, error -62
<6>usb 1-3: new full speed USB device using pxa27x-ohci and address 86
usb 1-3: device not accepting address 86, error -62
<6>usb 1-3: new full speed USB device using pxa27x-ohci and address 87
usb 1-3: device not accepting address 87, error -62
<3>hub 1-0:1.0: unable to enumerate USB device on port 3
我这边是通过ISP1106连接TD模块LC6311和310的 USB HOST PORT 3 的,下图是原理图,请大侠们帮忙分析一下有没有什么问题?
我也遇到和你一样的问题,不配置otg时,port3是可以正常工作的,配置otg时,port2可以正常使用,port3提示:usb 1-3: new full speed USB device using pxa27x-ohci and address 2
usb1-3: device v12d1 p1001 is not supported
楼上的问题解决了吗?
