| 5G模块使用的是RM500U-CN, 使用官方固件驱动后有两个ttyUSB0/1 口,在设置面却看不到sim卡插入; 自己编译的固件有5个ttyUSB0/1/2/3/4口,同样设置网络里面sim卡显示灰色的没有sim卡,这个要怎么处理? console:/ $ [ 55.069271][ T5] usb 4-1.4: new full-speed USB device number 3 using ehci-platform [ 55.266669][ T5] usb 4-1.4: not running at top speed; connect to a high speed hub [ 55.268155][ T5] usb 4-1.4: New USB device found, idVendor=1782, idProduct=4d00, bcdDevice=24.30 [ 55.268232][ T5] usb 4-1.4: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 55.268267][ T5] usb 4-1.4: Product: Gadget Serial [ 55.268300][ T5] usb 4-1.4: Manufacturer: spreadtrum with dwc3-gadget [ 58.922588][ T5] usb 4-1.4: USB disconnect, device number 3 [ 69.049270][ T5] usb 4-1.4: new high-speed USB device number 4 using ehci-platform [ 69.248786][ T5] usb 4-1.4: New USB device found, idVendor=2c7c, idProduct=0900, bcdDevice= 4.04 [ 69.249087][ T5] usb 4-1.4: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 69.249125][ T5] usb 4-1.4: Product: RM500U-CN [ 69.249153][ T5] usb 4-1.4: Manufacturer: Quectel [ 69.249349][ T5] usb 4-1.4: SerialNumber: 0123456789ABCDEF [ 69.263843][ T5] [dhd] CFG80211-ERROR) wl_cfg80211_netdev_notifier_call : wdev null.
