Can you try the following patch:

diff --git a/drivers/nut_usb.c b/drivers/nut_usb.c
index 494a1fa..4ca2691 100644
--- a/drivers/nut_usb.c
+++ b/drivers/nut_usb.c
@@ -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",
usb_strerror());
+         /* goto errout; */
        }

        return dev_h;


That should tell us what the error was, and see if we can continue past it.
