Linux 7.1 Removes Drivers For Long Obsolete Input Hardware: Bye Bus Mouse Support

Linux 7.1 is removing several long-obsolete input drivers, including bus mouse support, InPort/Microsoft/ATI XL busmouse, Logitech Bus Mouse, Palm Top PC 110 touchpad, ICS MicroClock MK712 touchscreen, CT82C710, and OLPC HGPK PS/2 protocol support. The release also adds a Charlieplex GPIO keypad driver, aw86927 support for the 86938 ASIC, and Chrome OS keyboard Fn-key keymap extension. The changes are largely maintenance-focused and reflect cleanup of legacy hardware support, with 3,374 deletions in the input pull.

Analysis

The economic signal here is not the driver removals themselves but the cadence: upstream kernel maintainers are continuing to prune dead code while expanding support for modern, embedded input paths. That is a quiet negative for legacy peripheral ecosystems because every removal raises the maintenance burden for vendors still shipping niche/industrial hardware and makes upstream support a lower-probability selling point in procurement cycles. The second-order winner is not a single hardware name so much as the broader class of OEMs shipping standardized HID/USB touch and keyboard stacks, where support risk is lower and time-to-market is faster.

For LOGI, the direct read-through is limited, but the removal of the old bus-mouse path reinforces how little residual value there is in legacy PS/2/ISA-era compatibility. That matters because any investor case that implicitly assumes long-tail replacement revenue from ancient enterprise devices is overstated; the remaining installed base is too small to move the needle, and the opportunity is increasingly displaced by low-cost commodity input devices. For INTC, the angle is broader: anything tied to x86 compatibility layers and pre-modern platform support is becoming an even smaller strategic asset, especially as kernel support gets trimmed at the margins.

ALPS is the most interesting name on a contrarian basis. The market may over-penalize a faint association with obsolete touchpad support, but the real takeaway is that broken or nonstandard protocol support is being deliberately de-emphasized, which reduces the odds that old platform-specific differentiation creates incremental revenue. If there is any benefit, it accrues to suppliers with current embedded touch solutions and firmware integration rather than legacy notebook touchpad content.

The catalyst horizon is measured in years, not days: this is a slow-burn secular cleanup, not an immediate earnings event. The risk to the short thesis is that the revenue contribution from these legacy lines is already immaterial, so any stock impact can fade quickly unless paired with a broader signal of design-win losses or channel destocking. The setup is therefore best expressed as relative value, not outright directional conviction.

Key Decisions for Investors

• Maintain a small underweight in LOGI vs. the broader hardware basket for 3-6 months; thesis is that legacy-compatibility stories have diminishing marginal value, but keep sizing modest because the direct revenue exposure is likely de minimis.
• Pair trade: long modern input/interface beneficiaries (e.g., HPQ or a PC/OEM proxy with current HID exposure) against short ALPS for 1-2 quarters if the market starts rewarding contemporary embedded content over legacy touchpad optionality.
• Avoid using INTC as a long-only proxy for platform compatibility support; if already long, hedge with a short-dated call spread on a PC OEM index or relative short vs. a more current embedded hardware name to isolate any secular platform-risk drift.
