We need to figure out why command complete event to reset command is not received and we get timeout for your bt chip. So first please provide kernel debug logs and hcidump while resuming (with timeout set to 10s). Also for kernel logs please make sure you have kernel prints timestamps enabled. hcidump -t kernel: echo "module bluetooth +pf" >/sys/kernel/debug/dynamic_debug/control echo "module btusb +pf" >/sys/kernel/debug/dynamic_debug/control -- Szymon K.
