Much of the Remarkable 2's design shows this level of suspicious hardware design choices that cripple extra functionality, functionality that wasn't advertised, but would have been possible had work not been done to prevent it. Beyond just bluetooth keyboards, while USB keyboards work on the Remarkable 1, support was apparently intentionally broken on the Remarkable 2. While otherwise completely supporting USB OTG, the USB port has been modified, apparently at a hardware level, to not provide power to devices. This appears to be related to the addition on the Remarkable 2 of an additional, physically-adjacent USB-protocol interface with a proprietary connector, for potential future accessories, which does provide power. For those who have made adapters, this proprietary interface supports USB keyboards quite readily: apparently, the possibility of developing a keyboard accessory in the future was sufficient motivation for the company to break standard keyboard support at a hardware level. While I have found the Remarkable enormously useful, that has largely been in spite of the company. Had I researched it more closely before purchasing it, I would have realized that the seeming openness (SSH access, Linux, a development community and unofficial third-party software repository) appears to have been forced on an otherwise hostile company by the GPLv3. So it is promising to see the same style of device with a manufacturer that actually supports it being open and adaptable.
