Or I guess you could grep through the kernel tree looking for a config CONFIGUSB, but that might waste more time than it saves. Otherwise the only possibility is to write everything from scratch for both sides of the USB connection. I'm no expert by far, but it seems like the most you could do is make an educated guess at which one worked. Knowing more about your use of the data, and how the data might change would help. please post lspci -k, lsusb -v, lsusb -t and a full dmesg log from the current setup. There is some wrong configuration setting or what device.c (11. This could be caused by changes in the xhci-hcd kernel module, or by udev/systemd changes. defconfig file changes default configuration. For example, we are using linux-yocto-rt kernel and create own receipt with name linux-yocto-rt and following files: linux-yocto-rtlinux-yocto-rt4.9.bb linux-yocto-rtlinux-yocto-rtdefconfig. The output of fdisk -l is the following : Computer fdisk -l Disk /dev/sda: 111,8 GiB, 120034123776 bytes, 234441648 sectors Units: sectors of 1 512 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disklabel type: dos Disk identifier: 0xe38ac795 Device Boot Start End. after some time xhci-hcd switches bus 003 down to usb2 mode and all devices work. One solution is to create own receipt and override default. Partitions can be marked read only or even write only. some of the devices connected to it fail. Partitions can be read or written at any offset for any span of bytes. Partitions can be used with and without formatting. I do not know about the error, but likely that if you are trying to use gadget, then this error is because it is missing a configuration stepâ¦the one turning it into mass storage.Ī question arises as to whether the nature of your data requires custom drivers, or if you could treat this like a partition (where the data partition might be VFAT or ext4 or even some custom file system typeâ¦maybe a binary unformatted partition) and simply allow the other end to look at a partition. That implies the driver at both sides will be custom. Please read for more information on using this driver.(on/off) USB Generic Serial Driver depends on USBSERIAL Say Y here if you want to use the generic USB serial driver. ![]() ![]() You can study the code and learn from it, but you will be writing your driver from scratch.
