I'm using usbfs. There's another odd thing I've seen often enough to make me suspicious that I'm doing something wrong. After opening a device and doing a few control requests to it, the first bulk write seems to work yet doesn't seem to reach the device. The ioctl() [USBDEVFS_BULK] returns the correct byte count yet the device doesn't respond. All subsequent bulk writes do work properly. Has anything like this been observed before? Does it perhaps mean that the output endpoint is in some sort of undesirable state, and, if so, is this a relatively common occurrence? Is there some way to prepare the device and/or endpoint so make the first bulk write more reliable? -- Dave Mielke | 2213 Fox Crescent | The Bible is the very Word of God.
