Re: [Nut-upsuser] Ablerex 625L USB version
Peter,
I have been doing some more testing and I find that if I modify
the libusb.c file to set a report size in libusb_get_report to 16 the
error messages go away. This is the code as it currently stands:
static int libusb_get_report(usb_dev_handle *udev, int ReportId,
unsigned char *raw_buf, int ReportSize )
{
int ReportSize_test = 16;
unsigned char raw_buf_test[ReportSize_test + 1];
int rc;
unsigned char *p_raw_buf_test;
upsdebugx(4, "Entering libusb_get_report, ReportSize: %i,
ReportSize_test: %i",ReportSize, ReportSize_test);
if (udev != NUL...

[PATCH 1/3] Skip non-feature HID reports
...s it is for powercom devices).
libusb_get_report() has:
ret = usb_control_msg(udev,
USB_ENDPOINT_IN + USB_TYPE_CLASS + USB_RECIP_INTERFACE,
0x01, /* HID_REPORT_GET */
ReportId+(0x03<<8), /* HID_REPORT_TYPE_FEATURE */
0, raw_buf, ReportSize, USB_TIMEOUT);
Hence, libusb_get_report() always requests the report ID as a feature
report, and never uses the report type that was stored.
This means that when HIDDumpTree() iterates over all reports that were
gathered from in the USB report descriptor, it tries to obtain their
valu...

This one made me scratch my head a bit.
I don't think it's unreasonable
