I recently purchased a RouterBoard 493G-based system. This board has a USB port that does not provide 5V power. I have been struggling to get this board to work with any USB device. I built a 2.6.39.4 OpenWrt kernel with EHCI, OHCI, USB storage, and USB printer support. I have attached a printer (with external power), a hard drive (with external power), and two different powered USB hubs attached to a thumb drive. None of these devices seem to be recognized by the kernel. /proc/bus/usb/devices consistently contains:

MxPS= 4 Ivl=256ms I have tried the newest revision of OpenWrt trunk and also r28423, "linux: ar71xx: add support for Mikrotik Routerboard RB493G". (The commiter of r28423 reported that a USB thumb drive worked for him when connected via a powered hub.) I am starting to think my board has a bad USB interface. Does anyone have any suggestions? Is anyone using the RB493G with a USB device attached? Is there anything I need in the kernel other than: kmod-usb-ohci kmod-usb-printer kmod-usb-storage kmod-usb2 and the items these selections pull in? -- Mike :wq _______________________________________________ openwrt-users mailing list [email protected] https://lists.openwrt.org/mailman/listinfo/openwrt-users
