Got 0xff's out on the pl2303, got nothing visible when characters sent in the other direction after setting 115200 8N1 on both sides. And, fwiw, I've been rmmod ch341 ; insmod $path/ch341.ko, where $path is the kernel module tree for the commit build, all from a 00013-gc510871 base kernel without rebooting. Not sure what the complaint about keys is about, I had not seen that before. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
