| Subject: usb: r8a66597-hcd: decrease timeout |
| |
| From: Chris Brandt <chris.brandt@renesas.com> |
| |
| commit dd14a3e9b92ac6f0918054f9e3477438760a4fa6 upstream. |
| |
| The timeout for BULK packets was 300ms which is a long time if other |
| endpoints or devices are waiting for their turn. Changing it to 50ms |
| greatly increased the overall performance for multi-endpoint devices. |
