Some devices supported by libsigrok need a firmware to be uploaded every time
-the device is connected to the PC (usually via USB), before it can be used.

- BBC Goertz Metrawatt M2110: Briefly press the "Start/Reset" button on the
interface panel on top.
- Digitek DT4000ZC: Briefly press the "RS232" button.
- - Gossen Metrawatt Metrahit devices: Power on the device with the "DATA"
- button pressed. Additionally, Metrahit 2x devices must be configured for
- interface "RS232".
+ - Gossen Metrawatt Metrahit 1x/2x devices, driver gmc-mh-1x-2x-rs232:
+ - Power on the device with the "DATA" button pressed.

+ - 'BD232' interface:
+ The multimeter must be configured for the respective interface type.
+ - 'SI232-II' interface ("PC Mode"):
+ The multimeter must be configured for interface type 'BD232' (all),
+ 'SI232 online' (28-29S) or 'SI232 store' (22-26x). The interface must
+ be configured to the same baud rate as the host (default 9600).
+ Multimeter and interface must be configured to the same address.
- Norma DM950: If the interface doesn't work (e.g. USB-RS232 converter), power
on the device with "FUNC" pressed (to power the interface from the DMM).
- PCE PCE-DM32: Briefly press the "RS232" button.
- Voltcraft VC-830: Press the "REL/PC" button for roughly 2 seconds.
-ALSA driver
------------
-
-The 'alsa' driver can be used to sample analog data using a PC's soundcard.
-I.e. the sound card can act as a simple oscilloscope (with some limitations)
-using commercial or DIY "sound card scope probe" cables.
-
-Since ALSA is a Linux-specific sound system, this driver will inherently
-only compile and work on Linux.
-
-We might write additional drivers to make a similar functionality available
-on other OSes at some point.

Link Instruments MSO-19
-----------------------
We plan to fix this though, so that it'll work on all other OSes, too.
