Can you try the following patch:
diff --git a/drivers/nut_usb.c b/drivers/nut_usb.c
index 494a1fa..4ca2691 100644
@@ -165,8 +165,8 @@ usb_dev_handle *nutusb_open(const char *port)
if (usb_clear_halt(dev_h, 0x81) < 0)
- upslogx(LOG_ERR, "Can't reset POWERWARE USB endpoint");
- goto errout;
+ upslogx(LOG_ERR, "Can't reset POWERWARE USB endpoint: %s",
+ /* goto errout; */
That should tell us what the error was, and see if we can continue past it.
