+.IX usbhid-dump
+.SH NAME
+usbhid-dump \- dump USB HID device report descriptors and streams
+.SH SYNOPSIS
+.B usbhid-dump
+[OPTION]...
+.SH DESCRIPTION
+.B usbhid-dump
+uses
+.B libusb
+to dump report descriptors and streams from HID (human interface device)
+interfaces of USB devices.  By default, it dumps HID interfaces of all
+connected USB devices, but could be limited to a subset of them, or to a single
+interface, using options.
+
+NOTE: usbhid-dump detaches kernel drivers from the interfaces it dumps and uses
+them exclusively, so no other program receives the input in the meantime.  The
+report descriptor dumping is instantaneous, but the stream dumping continues
+until terminated with SIGINT (^C from the terminal) or a timeout expires.
+
+If you accidentally start dumping a stream from the USB keyboard you use to
+control the terminal, the system will stop receiving the input and you won't
+be able to terminate usbhid-dump. Just stop your input and wait until the
+timeout expires. The stream dumping will stop, the keyboard will be
+reattached to the kernel driver and you will regain control.
+
+The default stream dumping timeout is 60 seconds and could be changed with the
+-t option.
+.SH OPTIONS
+.TP
+.B -h, --help
+Output a help message and exit.
+.TP
+.B -v, --version
+Output version information and exit.
+.TP
+.B -s, -a, --address=bus[:dev]
+Limit interfaces by bus number and device address. Both 1-255, decimal.
+Zeroes match any bus or device.
+.TP
+.B -d, -m, --model=vid[:pid]
+Limit interfaces by device vendor and product IDs. Both 1-FFFF, hexadecimal.
+Zeroes match any vendor or product.
+.TP
+.B -i, --interface=NUMBER
+Limit interfaces by number (0-254), decimal. 255 matches any interface.
+.TP
+.B -e, --entity=STRING
+The entity to dump: either "descriptor", "stream" or "all". The value can be
+abbreviated down to one letter. The default is "descriptor".
+.TP
+.B -t, --stream-timeout=NUMBER
+Stream interrupt transfer timeout, ms. Zero means infinity. The default is
+60000 (60 seconds).
+.TP
+.B -p, --stream-paused
+Start with the stream dump output paused.
+.TP
+.B -f, --stream-feedback
+Enable stream dumping feedback: print a dot to stderr for every transfer
+dumped.
+.SH SIGNALS
+.TP
+.B USR1/USR2
+Pause/resume stream dump output.
+.SH OUTPUT FORMAT
+.B usbhid-dump
+outputs dumps in chunks. Each chunk is separated by an empty line and starts
+with the following header line:
+
+BUS:DEVICE:INTERFACE:ENTITY TIMESTAMP
+
+Here, BUS, DEVICE and INTERFACE are bus, device and interface numbers
+respectively. ENTITY is either "DESCRIPTOR" or "STREAM". TIMESTAMP is
+timestamp in seconds since epoch.
+
+After the header the actual dump data follows as hex bytes. A descriptor
+chunk includes the whole report descriptor. Every stream chunk includes a
+whole report, usually, but if a report is bigger than endpoint's
+wMaxPacketSize, it will span several chunks.
+.SH EXAMPLES
+.TP
+Dump report descriptor for a device with address 3 on bus number 2:
+.B usbhid-dump -a 2:3
+
+.TP
+Dump report stream for a device with vendor ID 0x5543 and product ID 0x0005:
+.B usbhid-dump -m 5543:0005 -es
+
+.TP
+Dump report descriptor from interface 1 of a device with vendor ID 0x5543:
+.B usbhid-dump -m 5543 -i 1 -ed
+
+.TP
+Dump report streams from all HID interfaces of all USB devices (caution: you will lose control over the terminal if you use USB keyboard):
+.B usbhid-dump -es
