आरएनडीआईएस "समग्र डिवाइस"

Question

शुरू नहीं कर सकता है मैं एक आरएनडीआईएस समग्र डिवाइस विकसित कर रहा हूं जिसमें एक आरएनडीआईएस डिवाइस, एक यूएसबीनेट डिवाइस, एक मॉडेम डिवाइस और एक स्व-परिभाषित सीडीसी डिवाइस शामिल है।

पीसी Win7 32bit चला रहा है, और मैं डिफ़ॉल्ट RNDIS ड्राइवर का उपयोग कर रहा हूं। जब मैं केवल RNDIS डिवाइस के साथ विंडोज गणना का उत्तर देता हूं, तो सब कुछ ठीक काम करता है। लेकिन जब मैं सभी डिवाइस को डिस्क्रिप्टर में समग्र डिवाइस के रूप में लिखता हूं, तो विंडोज अभी भी सही ढंग से गणना करता है और अन्य 3 डिवाइस ठीक काम करते हैं, लेकिन आरएनडीआईएस डिवाइस "त्रुटि कोड 10 शुरू नहीं कर सकता" समस्या के साथ सामना करता है।

मैंने यूएसबी विश्लेषक के साथ यूएसबी डेटा प्रवाह का पता लगाया, पाया कि विंडोज आरएनडीआईएस चालक ने "कॉन्फ़िगरेशन सेट" के बाद संदेश संदेश प्रारंभ नहीं किया था।

समग्र डिवाइस वर्णनकर्ता के रूप में तैनात है:

Answer 1

मुझे मेरे ही सवाल का जवाब दो, मैं इस मुद्दे को पता लगा है समग्र डिवाइस। हालांकि समस्या हल हो गई है, फिर भी यह मुझे पहेली करता है।

आशा है कि यह नोट दूसरों को समान मुद्दों का सामना करने में मदद करेगा।
