こんにちは。ペンドライブ対応のためにLPC4088にUSB Host機能を実装しています。このコードはLPC QuickStartボード上では正しく動作しますが、当社独自のハードウェア上ではデバイスの列挙に失敗します。
具体的には、列挙時に `USB_Host_SendControlRequest()` が `HOST_SENDCONTROL_Successful` ではなく `HOST_SENDCONTROL_PipeError` を返します。問題は`HcdControlTransfer()`関数内にあると推測しており、おそらくパイプの設定に関連していると思われますが、根本原因を特定できていません。
何かご意見があれば大変ありがたいです。
