Alan (et al), Sorry again for the lateness of this testing, but here's some data from my Sony DCR-TRV38 camcorder. It seems to confirm what the others already discovered: the new patch seems to work much better (as long as the Windows-style initialization is done first). Here's the pertinent 'dmesg' output (with USB debugging enabled): ------------------------------ Vanilla 2.6.8.1 kernel, after plugging in a USB modem: usb 1-1: new device strings: Mfr=1, Product=2,

------------------------------ I also captured the output of '/var/log/messages', 'lsusb', and 'cat /proc/ bus/usb/devices' for all the permutations of kernels (vanilla 2.6.8.1, 2681 +patch1, and 2681+patches1&2) and USB device pluggings (no devices, USB modem only, and USB modem with camcorder). If any of that data is useful, let me know and I'll send it. Clearly the '/var/log/messages' file shows that the best condition was achieved with 2.6.8.1 with the first patch only (Windows-style init first): ---------- Oct 8 18:57:18 w6 kernel: usb 1-2: new full speed USB device using address 3 Oct 8 18:57:18 w6 kernel: Init get-descr: 18, maxpacket 64 Oct 8 18:57:20 w6 usb.agent[2173]: ... no modules for USB product 54c/c0/100 Oct 8 18:57:20 w6 usb.agent[2185]: ... no modules for USB product 54c/c0/100 Oct 8 18:57:20 w6 usb.agent[2192]: ... no modules for USB product 54c/c0/100 ---------- If there are other tests to run, please let me know.
