From e577ae94cd6317ddbc0ca9961c713e0621c107d1 Mon Sep 17 00:00:00 2001 From: Thinh Nguyen Date: Wed, 11 Dec 2024 00:32:13 +0000 Subject: [PATCH] usb: gadget: f_tcm: Increase stream count Some old builds of Microsoft Windows 10 UASP class driver reject UASP device with stream count of 2^4. To keep compatibility with both Linux and Windows, let's increase the stream count to 2^5. Also, internal tests show that stream count of 2^5 increases performance slightly.
