From 31543c17a9c15c1c6e9a6c8d39be10aaa184e4f1 Mon Sep 17 00:00:00 2001 From: hathach Date: Fri, 19 Jun 2026 23:00:55 +0700 Subject: dcd/ch58x: preserve the DEV_ADDR general-purpose bit on SET_ADDRESS dcd_edpt0_status_complete() wrote the full SET_ADDRESS wValue into R8_USB_DEV_AD, clobbering bit 7, which on CH58x is a user general-purpose flag (only bits [6:0] are the device address). Mask to 7 bits and preserve bit 7, matching the removed dcd_ch58x_usbfs.c. CH58x-scoped; other parts keep the full write.
