The m500s still will not sync with pilot-link 0.11.7 in -STABLE. An easily triggerable panic is another issue [1]. The pilot-link code first opens /dev/ugenX and then switches to /dev/ugenX.2, which is the HotSync endpoint for HotSyncs (endpoint 1 is listed as "Generic" in the endpoint descriptions). Relevant code is then:
i = 0; /* 0 or USBD_SHORT_XFER_OK */ if (ioctl(endpoint_fd, USB_SET_SHORT_XFER, &i) < 0) {
i = 50; if (ioctl(endpoint_fd, USB_SET_TIMEOUT, &i) < 0) {
later, writes to the endpoint go fine, but a read() on the endpoint_fd returns immediately with ETIMEDOUT if the USB_TIMEOUT is non-0. I've started following this through the ugen code, but get totally lost in kernel intricacies. Mostly I need a good way to dump debug info to the console while running though this code. Is kprintf() the right way to go? Will (over)using it cause timing problems in the ugen code?
I've got 5.1-RELEASE on a laptop, I'll check tomorrow if the situation is any different there (though cvsweb indicates not much has changed, really, recently, and NetBSD 1.6.1 fails just as miserably as FreeBSD 4.8 in doing anything with an m500.).

[1] open(/dev/ugen0) open(/dev/ugen0.2) ioctl(/dev/ugen0.2) is pretty much it, as documented in the pilot-link source.
