Created attachment 287009 [details] For "lsusb -v" it shows as "can't get device qualifier: Resource temporarily unavailable" Hi, 1. On recent ML v5.5.rc2 when i give cmd "lsusb -v", i see below errors from USB internal hubs.Same issue is seen on Yacto & Ubuntu desktop PCs. 2. There is no functionality issue seen so far... USB mounting, enumeration works as expected. 3. Issue started noticed from v4.14 onwards. The same issue is not seen on v4.1.49. Error: ====== Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub ... ... ... "can't get device qualifier: Resource temporarily unavailable can't get debug descriptor: Resource temporarily unavailable" 4. Does it mean while parsing/decoding USB device descriptor info from ACPI is something went wrong ? or something wrong from usb utils/libs ? I tried debugging, but i am not expert on USB so could not get the RC yet. 5. Can someone please help to share the fix details/possible fix, if you know it already. FYI... PFA logs for more info. Thanks Sudarshan
